12-15y+10y=10
Use the distributive property to multiply 3 by 4-5y.
12-5y=10
Combine -15y and 10y to get -5y.
-5y=10-12
Subtract 12 from both sides.
-5y=-2
Subtract 12 from 10 to get -2.
y=\frac{-2}{-5}
Divide both sides by -5.
y=\frac{2}{5}
Fraction \frac{-2}{-5} can be simplified to \frac{2}{5} by removing the negative sign from both the numerator and the denominator.
