x-5=20\left(-x+15\right)
Variable x cannot be equal to 15 since division by zero is not defined. Multiply both sides of the equation by 2\left(-x+15\right).
x-5=-20x+300
Use the distributive property to multiply 20 by -x+15.
x-5+20x=300
Add 20x to both sides.
21x-5=300
Combine x and 20x to get 21x.
21x=300+5
Add 5 to both sides.
21x=305
Add 300 and 5 to get 305.
x=\frac{305}{21}
Divide both sides by 21.
