Answer is v = -2
First we handle the numbers in the parenthesis as that’s first order of operation.
Multiply 3 x numbers in ( )
-7v + 3v -15 = -7
Now add 15 to both sides to isolate “v”
-7v + 3v -15 +15 = -7 + 15
Combine like terms
-4v = 8
Divide both sides by -4 to solve for “v”
-4/-4 v = 8/-4
v = -2
You can check your work by substituting (-2) for “v” in your equation.
(-7)(-2) + 3(-2-5) = -7
14 + (-21) = -7
-7 = -7
