x + 5(7x + 2) = 12x + 2(x + 1) – 3

x+35x+10=12x+2x+2-3
36x+10=14x+2-3
36x+10=14x-1
-14x -14x
22x+10=-1
-10 -10
22x=-11
22 22
x=-1/2

Correct?

Yep, looks good, and if you put -1/2 back into the original equation (a good way to check), you get

-18+10=-7-1
-8=-8

Since both sides are equal, -1/2 is a solution :)
