10.5+2y=7
Multiply 3 and 3.5 to get 10.5.
2y=7-10.5
Subtract 10.5 from both sides.
2y=-3.5
Subtract 10.5 from 7 to get -3.5.
y=\frac{-3.5}{2}
Divide both sides by 2.
y=\frac{-35}{20}
Expand \frac{-3.5}{2} by multiplying both numerator and the denominator by 10.
y=-\frac{7}{4}
Reduce the fraction \frac{-35}{20} to lowest terms by extracting and canceling out 5.
