16x=20\left(84-x\right)
Multiply 2 and 10 to get 20.
16x=1680-20x
Use the distributive property to multiply 20 by 84-x.
16x+20x=1680
Add 20x to both sides.
36x=1680
Combine 16x and 20x to get 36x.
x=\frac{1680}{36}
Divide both sides by 36.
x=\frac{140}{3}
Reduce the fraction \frac{1680}{36} to lowest terms by extracting and canceling out 12.
