21,25-5y=320y
Use the distributive property to multiply 5 by 4,25-y.
21,25-5y-320y=0
Subtract 320y from both sides.
21,25-325y=0
Combine -5y and -320y to get -325y.
-325y=-21,25
Subtract 21,25 from both sides. Anything subtracted from zero gives its negation.
y=\frac{-21,25}{-325}
Divide both sides by -325.
y=\frac{-2125}{-32500}
Expand \frac{-21,25}{-325} by multiplying both numerator and the denominator by 100.
y=\frac{17}{260}
