1240=100-0.05y+0.08y
Use the distributive property to multiply 0.05 by 2000-y.
1240=100+0.03y
Combine -0.05y and 0.08y to get 0.03y.
100+0.03y=1240
Swap sides so that all variable terms are on the left hand side.
0.03y=1240-100
Subtract 100 from both sides.
0.03y=1140
Subtract 100 from 1240 to get 1140.
y=\frac{1140}{0.03}
Divide both sides by 0.03.
y=\frac{114000}{3}
Expand \frac{1140}{0.03} by multiplying both numerator and the denominator by 100.
y=38000
Divide 114000 by 3 to get 38000.
