-\frac{21}{2}x=-63
Subtract 63 from both sides. Anything subtracted from zero gives its negation.
x=-63\left(-\frac{2}{21}\right)
Multiply both sides by -\frac{2}{21}, the reciprocal of -\frac{21}{2}.
x=\frac{-63\left(-2\right)}{21}
Express -63\left(-\frac{2}{21}\right) as a single fraction.
x=\frac{126}{21}
Multiply -63 and -2 to get 126.
x=6
Divide 126 by 21 to get 6.
