Put all the A's to one side of the equation and factor out the A

Explanation:

A = 3W - 5A

A + 5A = 3W

A(1 + 5) = 3W

A = $\frac{3 W}{6}$

practice exercises:

1. Solve for x in xy + 6y = 5x

2. Solve for z in $\frac{1}{x} + \frac{2}{y} + \frac{3}{z} = \frac{x}{y}$. Hint: think of putting everything on equal denominators.

Good luck!
