403+x=0\times 63\left(x+647\right)
Variable x cannot be equal to -647 since division by zero is not defined. Multiply both sides of the equation by x+647.
403+x=0\left(x+647\right)
Multiply 0 and 63 to get 0.
403+x=0
Anything times zero gives zero.
x=-403
Subtract 403 from both sides. Anything subtracted from zero gives its negation.
