distribute the -2
-2y -12 = y + 3 + 2y
now combine terms
-2y - 12 = 3y + 3
get the variables on one side and the real numbers on the other
-15 = 5y
divide by 5
-3 = y

We want "y" to be on "only one side"
first multipy the left side then simplify the right ... -2y -12 = 3y + 3
now simplify again by adding 12 to both sides... -2y = 3y + 15
and again by subtractin 3y from each side... -5y = 15
now divide by -5 y = -3
check your answer by inputting -3 -6 = -6
