45x+19000=w
Swap sides so that all variable terms are on the left hand side.
45x=w-19000
Subtract 19000 from both sides.
\frac{45x}{45}=\frac{w-19000}{45}
Divide both sides by 45.
x=\frac{w-19000}{45}
Dividing by 45 undoes the multiplication by 45.
x=\frac{w}{45}-\frac{3800}{9}
Divide w-19000 by 45.
