Question

Solve for P=2l+2w. Solve for w

Answer 1

`w = \frac P2 - l`

Explanation:

Solve for w by isolating the variable.

Solve for w

• 
  `P = 2l + 2w`

Factor 2 on the right-hand side

• 
  `P = 2(l + w)`

Divide both sides by 2

• 
  `\frac P2 = l + w`

Subtract L from both sides

• 
  `\frac P2 - l = w`

The solution for w is
`\frac P2 - l`
