1/2y + 6 + 3/2y = 2y - 6y -30 What is y?

1/2y + 6 + 3/2y = 2y - 6y -30
--------------------------------------------
Simplify each side
1/2y + 6 + 3/2y = 2y + -6y + -30
(Combine the like terms)
(1/2y + 3/2y) + 6 = (2y + -6y) + (-30)
2y+6=-4y+-30
2y+6=-4y-30
--------------------------------------------
add 4y to each side
2y+6+4y=-4y-30+4y
6y+6=-30
------------------------------------------------------------
Now subtract 6 from each side
6y+6-6=-30-6
6y=-36
---------------------------------------------------------------------------------
Finally, divide each side by 6
6y ÷ 6 = -36 ÷ 6
y = -6
=================================================================
Y = -6 is your answer
