How do you solve 12h-7=7h+18 as a 2-step equation

Step one:

12h-7=7h+18

12h-7h-7+7=7h-7h+18+7 Additive inverse

5h=25

Step two:

5h=25

5/5h=25/5 Multiplicative inverse

h=5

12h-7=7h+18

-7h - 7h

5h-7=18

+7 + 7

5h=25

5h/5 = 25/5

h=5

1. Subtract the 7h from both sides to cancel out the 7h (7h-7 and 12h-7)

equation becomes 5h-7=18

2. Add the 7 on the left side of the equation to both sides to cancel out the - 7 (-7+7 and 18+7)

equation becomes 5h=25

3. Divide by 5 to cancel out the 5h (5h/5 and 25/5)

equation becomes h=5 solving for h and giving you your final answer
