8+4.4+x+x=5\times 4
Multiply both sides by 4.
12.4+x+x=5\times 4
Add 8 and 4.4 to get 12.4.
12.4+2x=5\times 4
Combine x and x to get 2x.
12.4+2x=20
Multiply 5 and 4 to get 20.
2x=20-12.4
Subtract 12.4 from both sides.
2x=7.6
Subtract 12.4 from 20 to get 7.6.
x=\frac{7.6}{2}
Divide both sides by 2.
x=\frac{76}{20}
Expand \frac{7.6}{2} by multiplying both numerator and the denominator by 10.
x=\frac{19}{5}
Reduce the fraction \frac{76}{20} to lowest terms by extracting and canceling out 4.
