1500=100+x\left(-10\right)
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
100+x\left(-10\right)=1500
Swap sides so that all variable terms are on the left hand side.
x\left(-10\right)=1500-100
Subtract 100 from both sides.
x\left(-10\right)=1400
Subtract 100 from 1500 to get 1400.
x=\frac{1400}{-10}
Divide both sides by -10.
x=-140
Divide 1400 by -10 to get -140.
