2X+3-9X=0
Subtract 9X from both sides.
-7X+3=0
Combine 2X and -9X to get -7X.
-7X=-3
Subtract 3 from both sides. Anything subtracted from zero gives its negation.
X=\frac{-3}{-7}
Divide both sides by -7.
X=\frac{3}{7}
Fraction \frac{-3}{-7} can be simplified to \frac{3}{7} by removing the negative sign from both the numerator and the denominator.
