300-15x+12\left(30+15x\right)=69
Use the distributive property to multiply 15 by 20-x.
300-15x+360+180x=69
Use the distributive property to multiply 12 by 30+15x.
660-15x+180x=69
Add 300 and 360 to get 660.
660+165x=69
Combine -15x and 180x to get 165x.
165x=69-660
Subtract 660 from both sides.
165x=-591
Subtract 660 from 69 to get -591.
x=\frac{-591}{165}
Divide both sides by 165.
x=-\frac{197}{55}
Reduce the fraction \frac{-591}{165} to lowest terms by extracting and canceling out 3.
