Question

Solve for x
5(x+3)-3x=33

Answer 1

x = 9

Explanation:

use the distributive law to expand the bracket 5(x+3)

5(x+3) = 5x + 15

Substitute into the equation:

5x + 15 - 3x = 33

combine like factors (5x and - 3x):

5x + 15 - 3x = 33

2x + 15 = 33

subtract 15 from both sides

2x + 15 - 15 = 33 - 15

2x = 18

divide both sides by 2

2x ÷ 2 = 18 ÷ 2

x = 9

Answer 2

x=9

Explanation:

5(x+3)-3x=33

5x+15-3x=33

2x+15=33

2x=33-15

2x=18

x=9
