4x-3.1+3x=5.3
Add 3x to both sides.
7x-3.1=5.3
Combine 4x and 3x to get 7x.
7x=5.3+3.1
Add 3.1 to both sides.
7x=8.4
Add 5.3 and 3.1 to get 8.4.
x=\frac{8.4}{7}
Divide both sides by 7.
x=\frac{84}{70}
Expand \frac{8.4}{7} by multiplying both numerator and the denominator by 10.
x=\frac{6}{5}
Reduce the fraction \frac{84}{70} to lowest terms by extracting and canceling out 14.
