Question

Solve the following equation for gP = (g - 9)180 How do I solve this?

Answer 1

$P\text{ = (g - 9)}\cdot180$

Dividing by 180 at both sides:

$\frac{P}{180}\text{ = (g - 9)}\cdot\frac{180}{180}$$\frac{P}{180}=\text{ g - 9}$

Adding 9 at both sides:

$\frac{P}{180}\text{ + 9 = g - 9 + 9}$$g=\frac{P}{180}+9$
