64y+256y-4y-y=5040
Multiply both sides of the equation by 16, the least common multiple of 4,16.
320y-4y-y=5040
Combine 64y and 256y to get 320y.
316y-y=5040
Combine 320y and -4y to get 316y.
315y=5040
Combine 316y and -y to get 315y.
y=\frac{5040}{315}
Divide both sides by 315.
y=16
Divide 5040 by 315 to get 16.
