Question

7x + 3x - 18 = 6(x + 3)

Answer 1

x = 9

Explanation:

7x + 3x - 18 = 6(x + 3) ← distribute parenthesis by 6

10x - 18 = 6x + 18 ( subtract 6x from both sides )

4x - 18 = 18 ( add 18 to both sides )

4x = 36 ( divide both sides by 4 )

x = 9

Answer 2

x=9, therefore 72=72

Explanation:

I just distributed.
