2\left(3x-5\right)-5\left(x-3\right)=20\left(x+5\right)
Multiply both sides of the equation by 10, the least common multiple of 5,2.
6x-10-5\left(x-3\right)=20\left(x+5\right)
Use the distributive property to multiply 2 by 3x-5.
6x-10-5x+15=20\left(x+5\right)
Use the distributive property to multiply -5 by x-3.
x-10+15=20\left(x+5\right)
Combine 6x and -5x to get x.
x+5=20\left(x+5\right)
Add -10 and 15 to get 5.
x+5=20x+100
Use the distributive property to multiply 20 by x+5.
x+5-20x=100
Subtract 20x from both sides.
-19x+5=100
Combine x and -20x to get -19x.
-19x=100-5
Subtract 5 from both sides.
-19x=95
Subtract 5 from 100 to get 95.
x=\frac{95}{-19}
Divide both sides by -19.
x=-5
Divide 95 by -19 to get -5.
