-2.2x+3-1.7x=0
Subtract 1.7x from both sides.
-3.9x+3=0
Combine -2.2x and -1.7x to get -3.9x.
-3.9x=-3
Subtract 3 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-3}{-3.9}
Divide both sides by -3.9.
x=\frac{-30}{-39}
Expand \frac{-3}{-3.9} by multiplying both numerator and the denominator by 10.
x=\frac{10}{13}
Reduce the fraction \frac{-30}{-39} to lowest terms by extracting and canceling out -3.
