x+0.79-0.3x=1.91
Subtract 0.3x from both sides.
0.7x+0.79=1.91
Combine x and -0.3x to get 0.7x.
0.7x=1.91-0.79
Subtract 0.79 from both sides.
0.7x=1.12
Subtract 0.79 from 1.91 to get 1.12.
x=\frac{1.12}{0.7}
Divide both sides by 0.7.
x=\frac{112}{70}
Expand \frac{1.12}{0.7} by multiplying both numerator and the denominator by 100.
x=\frac{8}{5}
Reduce the fraction \frac{112}{70} to lowest terms by extracting and canceling out 14.
