Answer 3

First multiply, what is 3 x 4?

Answer 4

12

Answer 5

Correct, so we have 12 - 3 x 7 = 3(x - 7)

Still multiplying, what is 3 x 7?

Answer 6

21

Answer 7

Correct, so we have 12 - 21 = 3(x - 7)

What is 12 - 21?

Answer 8

-9?

Answer 9

Yes, so we have -9 = 3(x - 7) and to solve this, you must simplify the equation to have

3x - 21 = -9

So we first, add 21 to boh sides of the equation

3x - + 21 = -9 + 21

3x = -9 + 21

Answer 10

What is -9 + 21

Answer 11

12

Answer 12

Answer 13

x = 12/3
