Hey there! :)

-3(5a - 5) + 6a = 31 - 5a

Simplify! -15a + 15 + 6a = 31 - 5a

We must get all variables to one side and everything else to the other so that we can add like terms, so we can start by subtracting 15 from both sides. Additionally, add 5a to both sides.

-15a + 6a + 5a = 31 - 15

Simplify.-4a = 16

Divide both sides by -4.

-4a ÷ -4 = 16 ÷ -4

Simplify.

a = -4

~Hope this helped! :)
