4.7+4.7+x+x=5\times 3
Multiply both sides by 3.
9.4+x+x=5\times 3
Add 4.7 and 4.7 to get 9.4.
9.4+2x=5\times 3
Combine x and x to get 2x.
9.4+2x=15
Multiply 5 and 3 to get 15.
2x=15-9.4
Subtract 9.4 from both sides.
2x=5.6
Subtract 9.4 from 15 to get 5.6.
x=\frac{5.6}{2}
Divide both sides by 2.
x=\frac{56}{20}
Expand \frac{5.6}{2} by multiplying both numerator and the denominator by 10.
x=\frac{14}{5}
Reduce the fraction \frac{56}{20} to lowest terms by extracting and canceling out 4.
