0.4+0.6x=0.7
Combine x and -0.4x to get 0.6x.
0.6x=0.7-0.4
Subtract 0.4 from both sides.
0.6x=0.3
Subtract 0.4 from 0.7 to get 0.3.
x=\frac{0.3}{0.6}
Divide both sides by 0.6.
x=\frac{3}{6}
Expand \frac{0.3}{0.6} by multiplying both numerator and the denominator by 10.
x=\frac{1}{2}
Reduce the fraction \frac{3}{6} to lowest terms by extracting and canceling out 3.
