x+0.4x=37
Add 0.4x to both sides.
1.4x=37
Combine x and 0.4x to get 1.4x.
x=\frac{37}{1.4}
Divide both sides by 1.4.
x=\frac{370}{14}
Expand \frac{37}{1.4} by multiplying both numerator and the denominator by 10.
x=\frac{185}{7}
Reduce the fraction \frac{370}{14} to lowest terms by extracting and canceling out 2.
