7+x=0\times 80\left(x+11\right)
Variable x cannot be equal to -11 since division by zero is not defined. Multiply both sides of the equation by x+11.
7+x=0\left(x+11\right)
Multiply 0 and 80 to get 0.
7+x=0
Anything times zero gives zero.
x=-7
Subtract 7 from both sides. Anything subtracted from zero gives its negation.
