5\times 2\left(x-5\right)-3\left(2x+3\right)=5x+2\left(-x-25\right)
Multiply both sides of the equation by 15, the least common multiple of 3,5,15.
10\left(x-5\right)-3\left(2x+3\right)=5x+2\left(-x-25\right)
Multiply 5 and 2 to get 10.
10x-50-3\left(2x+3\right)=5x+2\left(-x-25\right)
Use the distributive property to multiply 10 by x-5.
10x-50-6x-9=5x+2\left(-x-25\right)
Use the distributive property to multiply -3 by 2x+3.
4x-50-9=5x+2\left(-x-25\right)
Combine 10x and -6x to get 4x.
4x-59=5x+2\left(-x-25\right)
Subtract 9 from -50 to get -59.
4x-59=5x+2\left(-x\right)-50
Use the distributive property to multiply 2 by -x-25.
4x-59-5x=2\left(-x\right)-50
Subtract 5x from both sides.
-x-59=2\left(-x\right)-50
Combine 4x and -5x to get -x.
-x-59-2\left(-x\right)=-50
Subtract 2\left(-x\right) from both sides.
-x-59-2\left(-1\right)x=-50
Multiply -1 and 2 to get -2.
-x-59+2x=-50
Multiply -2 and -1 to get 2.
x-59=-50
Combine -x and 2x to get x.
x=-50+59
Add 59 to both sides.
x=9
Add -50 and 59 to get 9.
