# Given the equation p = 2w + 2l, solve for w.

**Solution:**

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.

The standard form of a linear equation in one variable is of the form Ax + B = 0.

Given equation,

p = 2w + 2l

⇒ 2w = p - 2l

⇒ w = (p - 2l) / 2

⇒ w = p/2 - l

**Example:** Solve for z if y = 5x - 25 z

Given equation y = 5x - 25 z

⇒ 25z = 5x - y

⇒ z = (1/5)x - (y/25)

## Given the equation p = 2w + 2l, solve for w.

**Summary: **

The value of ‘w’ in p = 2w + 2l is = p/2 - l
