0.4x+0.2x=5.58
Add 0.2x to both sides.
0.6x=5.58
Combine 0.4x and 0.2x to get 0.6x.
x=\frac{5.58}{0.6}
Divide both sides by 0.6.
x=\frac{558}{60}
Expand \frac{5.58}{0.6} by multiplying both numerator and the denominator by 100.
x=\frac{93}{10}
Reduce the fraction \frac{558}{60} to lowest terms by extracting and canceling out 6.
