10y=2\left(4\times 5+2\right)
Multiply both sides of the equation by 10, the least common multiple of 2,5.
10y=2\left(20+2\right)
Multiply 4 and 5 to get 20.
10y=2\times 22
Add 20 and 2 to get 22.
10y=44
Multiply 2 and 22 to get 44.
y=\frac{44}{10}
Divide both sides by 10.
y=\frac{22}{5}
Reduce the fraction \frac{44}{10} to lowest terms by extracting and canceling out 2.
