\frac{3\left(X+1\right)}{6}+\frac{X-1}{6}=X
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 2 and 6 is 6. Multiply \frac{X+1}{2} times \frac{3}{3}.
\frac{3\left(X+1\right)+X-1}{6}=X
Since \frac{3\left(X+1\right)}{6} and \frac{X-1}{6} have the same denominator, add them by adding their numerators.
\frac{3X+3+X-1}{6}=X
Do the multiplications in 3\left(X+1\right)+X-1.
\frac{4X+2}{6}=X
Combine like terms in 3X+3+X-1.
\frac{2}{3}X+\frac{1}{3}=X
Divide each term of 4X+2 by 6 to get \frac{2}{3}X+\frac{1}{3}.
\frac{2}{3}X+\frac{1}{3}-X=0
Subtract X from both sides.
-\frac{1}{3}X+\frac{1}{3}=0
Combine \frac{2}{3}X and -X to get -\frac{1}{3}X.
-\frac{1}{3}X=-\frac{1}{3}
Subtract \frac{1}{3} from both sides. Anything subtracted from zero gives its negation.
X=-\frac{1}{3}\left(-3\right)
Multiply both sides by -3, the reciprocal of -\frac{1}{3}.
X=\frac{-\left(-3\right)}{3}
Express -\frac{1}{3}\left(-3\right) as a single fraction.
X=\frac{3}{3}
Multiply -1 and -3 to get 3.
X=1
Divide 3 by 3 to get 1.
