0.05y-15=105-0.1y
Use the distributive property to multiply 0.05 by y-300.
0.05y-15+0.1y=105
Add 0.1y to both sides.
0.15y-15=105
Combine 0.05y and 0.1y to get 0.15y.
0.15y=105+15
Add 15 to both sides.
0.15y=120
Add 105 and 15 to get 120.
y=\frac{120}{0.15}
Divide both sides by 0.15.
y=\frac{12000}{15}
Expand \frac{120}{0.15} by multiplying both numerator and the denominator by 100.
y=800
Divide 12000 by 15 to get 800.
