Question

Describe the steps you would take to solve for the variable x in the following

Answer 1

Answer:

x =  19

Step-by-step explanation:

1. add 31 on both sides (you wanna get the "x" by itself)

ex: 2x - 31 = 7

          +31   +31

2. the 31s cancel each other out so now you add 31 + 7

2x       =  7

           +31

___________

             38

3. divide 2 on both sides so the 2s cancel each other out and only the x is left

ex: 2x / 2 = x         38 ( the 38 stands alone)

4. now divide 38/2 and you have your answer

X= 19
