8.4x+4800=-0.4\left(20x+12000\right)+20.6x
Use the distributive property to multiply 0.6 by 14x+8000.
8.4x+4800=-8x-4800+20.6x
Use the distributive property to multiply -0.4 by 20x+12000.
8.4x+4800=12.6x-4800
Combine -8x and 20.6x to get 12.6x.
8.4x+4800-12.6x=-4800
Subtract 12.6x from both sides.
-4.2x+4800=-4800
Combine 8.4x and -12.6x to get -4.2x.
-4.2x=-4800-4800
Subtract 4800 from both sides.
-4.2x=-9600
Subtract 4800 from -4800 to get -9600.
x=\frac{-9600}{-4.2}
Divide both sides by -4.2.
x=\frac{-96000}{-42}
Expand \frac{-9600}{-4.2} by multiplying both numerator and the denominator by 10.
x=\frac{16000}{7}
Reduce the fraction \frac{-96000}{-42} to lowest terms by extracting and canceling out -6.
