Question

What is 3(2x +7x - 5 )

Answer 1

27x - 15 is your expression

Explanation:

3 x 2x = 6x and 3 x 7x = 21x so 21x + 6x = 27x and 3 x 5 = 15 so 27x - 15 is your expression

Answer 2

x = 15/27

Explanation:

3(2x + 7x - 5)

Distribute the 3

6x + 21x - 15

Combine like terms

27x - 15 = 0

27x = 15

x = 15/27
