-3.5x-3=0
Swap sides so that all variable terms are on the left hand side.
-3.5x=3
Add 3 to both sides. Anything plus zero gives itself.
x=\frac{3}{-3.5}
Divide both sides by -3.5.
x=\frac{30}{-35}
Expand \frac{3}{-3.5} by multiplying both numerator and the denominator by 10.
x=-\frac{6}{7}
Reduce the fraction \frac{30}{-35} to lowest terms by extracting and canceling out 5.
