0.04x+640-0.02x=1120
Use the distributive property to multiply 0.02 by 32000-x.
0.02x+640=1120
Combine 0.04x and -0.02x to get 0.02x.
0.02x=1120-640
Subtract 640 from both sides.
0.02x=480
Subtract 640 from 1120 to get 480.
x=\frac{480}{0.02}
Divide both sides by 0.02.
x=\frac{48000}{2}
Expand \frac{480}{0.02} by multiplying both numerator and the denominator by 100.
x=24000
Divide 48000 by 2 to get 24000.
