So that’s going to be 14 absolute values of x plus 7, 14 times answera absolute value of x plus 7. To log in and use all the features of Khan Academy, please enable JavaScript in your browser. The 4 and the negative 4 cancel out, and that was intentional.

Now the key here– at first it looks kind of daunting. We can’t, of course, only do that a,gebra the right-hand side. So just as answes, we’ve now solved for the absolute value of x plus 7, but we really need to solve for x. Discrete mathematics and probability. Let me just rewrite this equation so that the absolute values really pop out. We’re just subtracting 7 from both sides. Under each lesson you will find theory, examples and video lessons. So let’s try to do that. So that’s going to be equal to 2.

Polynomials and radical expressions.

So that’s one possibility for x. Algebra 2 is the third math course in high school and will guide you through among other things linear equations, inequalities, graphs, matrices, polynomials and radical expressions, quadratic equations, functions, exponential and logarithmic expressions, sequences and series, probability and trigonometry.

So you could almost treat this expression– the absolute value of x plus 7, you can just treat it as a variable, and then once you solve for that, it becomes a simpler absolute value problem. It’s this complex equation.

Algebra 2 Rational expressions Overview Variation Operate on rational expressions. Search Pre-Algebra All courses. Easiest way to get rid of it is to add 6 times the absolute value of x plus 7 to the right-hand side. So our left-hand side, if I have 8 of something– and in this case the something is absolute values of x plus 7’s– but if I have 8 of something and I add 6 of that same something, I now have 14 of that something.

You’ll see what I mean. Let’s try to solve for not x first. The negative 6 and the 6 x plus 7’s cancel out, or absolute values of x plus 7’s cancel out, and anwwers was intentional. And then we’re left with 6 minus 4, which is just 2. Algebra 2 Equations and inequalities Overview Solve equations and simplify expressions Line plots and stem-and-leaf plots Absolute value Solve inequalities. Algebra 2 Exponential and logarithmic functions Overview Exponential functions Logarithm and logarithm functions Logarithm property.

Easiest way is to subtract 4 right over there, but if we do it on the left-hand side, we have to do it on the right-hand side as well. Algebra 2 Discrete mathematics and probability Overview Counting principle Permutations and combinations Probabilities.

Solve absolute value equations. This Algebra 2 math course is divided into 13 chapters and each chapter is divided into several lessons.

And so what does this get us? So let’s do that, so plus 6 times the absolute value of x plus 7. Algebra 2 How to graph functions and linear equations Overview Functions and linear equations Graph functions and relations Graph inequalities. And just think about that for a second.

How to graph functions and linear equations.

Worked example: absolute value equation with two solutions

So now let’s just solve for x. So I want to get all of the absolute values of answera plus 7 on the left-hand side, so I want to get rid of this one on the right-hand side.

Now just as promised, we want to solve for the absolute value of x plus 7, so let’s divide both sides by 14 to get rid of that coefficient there, or that factor, or whatever you want to call it, the thing that’s multiplying the absolute value of x plus 7.
