X-\frac{1}{7}-\frac{1}{2}X=0
Subtract \frac{1}{2}X from both sides.
\frac{1}{2}X-\frac{1}{7}=0
Combine X and -\frac{1}{2}X to get \frac{1}{2}X.
\frac{1}{2}X=\frac{1}{7}
Add \frac{1}{7} to both sides. Anything plus zero gives itself.
X=\frac{1}{7}\times 2
Multiply both sides by 2, the reciprocal of \frac{1}{2}.
X=\frac{2}{7}
Multiply \frac{1}{7} and 2 to get \frac{2}{7}.
