2.4+2y=20
Multiply 6 and 0.4 to get 2.4.
2y=20-2.4
Subtract 2.4 from both sides.
2y=17.6
Subtract 2.4 from 20 to get 17.6.
y=\frac{17.6}{2}
Divide both sides by 2.
y=\frac{176}{20}
Expand \frac{17.6}{2} by multiplying both numerator and the denominator by 10.
y=\frac{44}{5}
Reduce the fraction \frac{176}{20} to lowest terms by extracting and canceling out 4.
