20y+56=14y+7\left(3\times 4+1\right)
Multiply both sides of the equation by 28, the least common multiple of 7,2,4.
20y+56=14y+7\left(12+1\right)
Multiply 3 and 4 to get 12.
20y+56=14y+7\times 13
Add 12 and 1 to get 13.
20y+56=14y+91
Multiply 7 and 13 to get 91.
20y+56-14y=91
Subtract 14y from both sides.
6y+56=91
Combine 20y and -14y to get 6y.
6y=91-56
Subtract 56 from both sides.
6y=35
Subtract 56 from 91 to get 35.
y=\frac{35}{6}
Divide both sides by 6.
