4864=x\times 21+x\left(-5\right)
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
4864=16x
Combine x\times 21 and x\left(-5\right) to get 16x.
16x=4864
Swap sides so that all variable terms are on the left hand side.
x=\frac{4864}{16}
Divide both sides by 16.
x=304
Divide 4864 by 16 to get 304.
