0.55y+7=8.75+0.35y
Use the distributive property to multiply 0.35 by 25+y.
0.55y+7-0.35y=8.75
Subtract 0.35y from both sides.
0.2y+7=8.75
Combine 0.55y and -0.35y to get 0.2y.
0.2y=8.75-7
Subtract 7 from both sides.
0.2y=1.75
Subtract 7 from 8.75 to get 1.75.
y=\frac{1.75}{0.2}
Divide both sides by 0.2.
y=\frac{175}{20}
Expand \frac{1.75}{0.2} by multiplying both numerator and the denominator by 100.
y=\frac{35}{4}
Reduce the fraction \frac{175}{20} to lowest terms by extracting and canceling out 5.
