5y = 3y + 12 5y - 3y = (3y - 3y) + 12 2y = 12 y = 6

8a+4a=144 12a=144 12a/12=144/12 A=144

-9h-6+12h+40=22 -9h+12h=22-40+6 3h=-12 h=-4

The equation 6 + y = 12 is a simple equation in one variable. If you add 6 to both sides of the equals sign, you get y = 18, and that is the solution.

Answer:12y=132y=132/12=11

The solution to this equation is that h is equal to -4. You can substitute this value for h into the equation to get -4 x -9 - 6 plus 12 x -4 plus 40 equals 22, or 36 - 6 plus - 48 plus 40 equals 22.

5y = 3y + 12 5y - 3y = (3y - 3y) + 12 2y = 12 y = 6
