-63\times 12=-x\left(-8,4\right)
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 63x, the least common multiple of x;-63.
-756=-x\left(-8,4\right)
Multiply -63 and 12 to get -756.
-756=8,4x
Multiply -1 and -8,4 to get 8,4.
8,4x=-756
Swap sides so that all variable terms are on the left hand side.
x=\frac{-756}{8,4}
Divide both sides by 8,4.
x=\frac{-7560}{84}
Expand \frac{-756}{8,4} by multiplying both numerator and the denominator by 10.
x=-90
Divide -7560 by 84 to get -90.
