Question

What is the first step to solving for x in the equation 9x-7=10? how would you check your solution

Answer 1

The first step in solving for x would be adding 7 to both sides. Once you find what x equals you can check your solution by filling in x and seeing if it equals 10.

Explanation:

9x-7=10

add 7 to both sides

9x= 17

divide both sides by 9

x = 17/9

To check:

9(17/9)-7 = 10

10=10
