Question

How do i solve
3(x+3)=18

Answer 1

Distribution
3 times X is 3x and 3 times 3 is 9
So
3x+9 =18
-9 -9
0. 9
3x=9

9/3 is 3
X=3

Answer 2

Solve for x.
3(x+3)=18
Distribute the brackets.
3*x=3x
3*3=9
3x+9=18
Subtract 9 from both sides.
(3x+9)-9=(18)-9
3x=9
Divide both sides by 3.
(3x)/3=(9)/3
x=3

Hope this helps.
