10\left(2x-5\right)+15\left(x+2\right)=20\left(5-2x\right)-12\left(6-7x\right)-60x
Multiply both sides of the equation by 60, the least common multiple of 6,4,3,5.
20x-50+15\left(x+2\right)=20\left(5-2x\right)-12\left(6-7x\right)-60x
Use the distributive property to multiply 10 by 2x-5.
20x-50+15x+30=20\left(5-2x\right)-12\left(6-7x\right)-60x
Use the distributive property to multiply 15 by x+2.
35x-50+30=20\left(5-2x\right)-12\left(6-7x\right)-60x
Combine 20x and 15x to get 35x.
35x-20=20\left(5-2x\right)-12\left(6-7x\right)-60x
Add -50 and 30 to get -20.
35x-20=100-40x-12\left(6-7x\right)-60x
Use the distributive property to multiply 20 by 5-2x.
35x-20=100-40x-72+84x-60x
Use the distributive property to multiply -12 by 6-7x.
35x-20=28-40x+84x-60x
Subtract 72 from 100 to get 28.
35x-20=28+44x-60x
Combine -40x and 84x to get 44x.
35x-20=28-16x
Combine 44x and -60x to get -16x.
35x-20+16x=28
Add 16x to both sides.
51x-20=28
Combine 35x and 16x to get 51x.
51x=28+20
Add 20 to both sides.
51x=48
Add 28 and 20 to get 48.
x=\frac{48}{51}
Divide both sides by 51.
x=\frac{16}{17}
Reduce the fraction \frac{48}{51} to lowest terms by extracting and canceling out 3.
