Question

Solve for w.
4w-9=71

Answer 1

w = 20.

Explanation:

4w - 9 = 71

First add 9 to both sides of the equation:

4w - 9 + 9 = 71 + 9

4w = 80

Now divide both sides by 4:

w = 80/4 = 20

Answer 2

w = 20

Explanation:

4w-9=71

Add 9 to each side

4w-9+9=71+9

4w = 80

Divide by 4

4w/4 = 80/4

w = 20
