\left(x-150\right)\times 300=\left(x+150\right)\times 200
Variable x cannot be equal to any of the values -150,150 since division by zero is not defined. Multiply both sides of the equation by \left(x-150\right)\left(x+150\right), the least common multiple of x+150,x-150.
300x-45000=\left(x+150\right)\times 200
Use the distributive property to multiply x-150 by 300.
300x-45000=200x+30000
Use the distributive property to multiply x+150 by 200.
300x-45000-200x=30000
Subtract 200x from both sides.
100x-45000=30000
Combine 300x and -200x to get 100x.
100x=30000+45000
Add 45000 to both sides.
100x=75000
Add 30000 and 45000 to get 75000.
x=\frac{75000}{100}
Divide both sides by 100.
x=750
Divide 75000 by 100 to get 750.
