Question

Given ƒ(x) = −15x − 13, find x when ƒ(x) = −28

Answer 1

1

Explanation:

So since both equations equal f(x), we can set them equal to each other

-15x - 13 = -28

Our next step is to get x by itself on one side of the equation. To do this, you:

Add 13 to both sides

-15x = -15

Divide both sides by -15

x = 1
