Question

-3(x+5)+3=12

Answer 1

-3(x+5)+3=12

-3x - 15 + 3 = 12
-3x - 12 = 12
-3x = 24
x = -8

Answer 2

you have to solve for x.

-3(x+5)+3
distribute.
you'll get...
-3x-15+3=12
combine like terms.
-3x-12=12
solve for x.
add 12 to both sides.
-3x=24
divide both sides by -3
x=-8

plug the-8 back in to x to see if your answer is right.

-3(x+5)+3=12
-3(-8+5)+3=?
-3(-3)+3=?
9+3=?
12=12

Answer 3
