x-3.1x=3
Subtract 3.1x from both sides.
-2.1x=3
Combine x and -3.1x to get -2.1x.
x=\frac{3}{-2.1}
Divide both sides by -2.1.
x=\frac{30}{-21}
Expand \frac{3}{-2.1} by multiplying both numerator and the denominator by 10.
x=-\frac{10}{7}
Reduce the fraction \frac{30}{-21} to lowest terms by extracting and canceling out 3.
