Question

Solve each formula for the indicated varible,P=2w+21, for w

Answer 1

`(P-21)/(2) =w`

Explanation:

To solve for w use the properties of equality. A property of equality states that if you do the same thing to both sides it is still equal.

First, subtract 21 from both sides

1) P-21=2w

Then, divide both sides by 2

2) (P-21)/2=w

This formula allows you to solve for w by plugging in a P-value.
