6x+3-2x=0
Subtract 2x from both sides.
4x+3=0
Combine 6x and -2x to get 4x.
4x=-3
Subtract 3 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-3}{4}
Divide both sides by 4.
x=-\frac{3}{4}
Fraction \frac{-3}{4} can be rewritten as -\frac{3}{4} by extracting the negative sign.
