Question

3 (3x + 10) = 120 solve for x and simplify your answer as much as possible

Answer 1

x=10

Step by Step:
3(3x+10)=120
Take the 3 that is not in the parentheses and multiply it with the 3x and the 10 to make
9x+30=120
Cross the sides so the X variable is by itself
9x=120-30
Subtract
9x=90
Simplify (90/9=10)
X=10

Answer 2

x = 10

Explanation:

3(3x+10) = 120

Expand: 9x + 30 = 120

Cross sides: 9x = 120-30

Simplify: 9x = 90

Divide : x = 90\9
