10\left(x-\frac{3x}{5}\right)-5\left(x-\frac{3x}{5}\right)=100
Multiply both sides of the equation by 10, the least common multiple of 5,2.
10x+10\left(-\frac{3x}{5}\right)-5\left(x-\frac{3x}{5}\right)=100
Use the distributive property to multiply 10 by x-\frac{3x}{5}.
10x-2\times 3x-5\left(x-\frac{3x}{5}\right)=100
Cancel out 5, the greatest common factor in 10 and 5.
10x-6x-5\left(x-\frac{3x}{5}\right)=100
Multiply -2 and 3 to get -6.
4x-5\left(x-\frac{3x}{5}\right)=100
Combine 10x and -6x to get 4x.
20x-25\left(x-\frac{3x}{5}\right)=500
Multiply both sides of the equation by 5.
100x-5\times 25\left(x-\frac{3x}{5}\right)=2500
Multiply both sides of the equation by 5.
100x-125\left(x-\frac{3x}{5}\right)=2500
Multiply -5 and 25 to get -125.
100x-125x+125\times \frac{3x}{5}=2500
Use the distributive property to multiply -125 by x-\frac{3x}{5}.
100x-125x+25\times 3x=2500
Cancel out 5, the greatest common factor in 125 and 5.
100x-125x+75x=2500
Multiply 25 and 3 to get 75.
100x-50x=2500
Combine -125x and 75x to get -50x.
50x=2500
Combine 100x and -50x to get 50x.
x=\frac{2500}{50}
Divide both sides by 50.
x=50
Divide 2500 by 50 to get 50.
