2w+3.4=42
Combine w and w to get 2w.
2w=42-3.4
Subtract 3.4 from both sides.
2w=38.6
Subtract 3.4 from 42 to get 38.6.
w=\frac{38.6}{2}
Divide both sides by 2.
w=\frac{386}{20}
Expand \frac{38.6}{2} by multiplying both numerator and the denominator by 10.
w=\frac{193}{10}
Reduce the fraction \frac{386}{20} to lowest terms by extracting and canceling out 2.
