Question

Solve the equation. h + 20 = 35 – 4h

Answer 1

H+20=35-4h
+4h +4h Add 4 on both sides to cancel out 4h
--------------------
5H+20=35
-20 -20
------------------
5h=15
---------- Divide 5 on both sides to get 5 by itself
5 5

H=3

Answer 2

First, you have to get all the variables on one side, so you use inverse operations. 

 h+20=35-4h
 +4h         +4h
------------------
5h+20=35

Next, you solve as a two-step equation.

5h+20=35
    -20  -20
-----------------
5h=15

(1/5) 5h+15 (1/5)

h=3
