Question

Solve the equation. 3(2w – 7) = 3
w = 4
w = 5/3
w = -1/5
w = 7/5

Answer 1

If there's a number aside something in parenthesis, you multiply everything in the parenthesis by that number

So

Answer 2

The left side becomes 6w -21 (cause 3x2w = 6w, and 3x7 = 21 )

Answer 3

You can add 21 to both sides, and get 6w = 24

Answer 4

Divide by 6 on both sides, you get w = 4.

Answer 5

Understand?
