-0.02x+0.1x+40=56
Use the distributive property to multiply 0.1 by x+400.
0.08x+40=56
Combine -0.02x and 0.1x to get 0.08x.
0.08x=56-40
Subtract 40 from both sides.
0.08x=16
Subtract 40 from 56 to get 16.
x=\frac{16}{0.08}
Divide both sides by 0.08.
x=\frac{1600}{8}
Expand \frac{16}{0.08} by multiplying both numerator and the denominator by 100.
x=200
Divide 1600 by 8 to get 200.
