3\left(2x+5x\right)-4\left(x-5\right)=12\left(x-4\right)-2\left(4x+7\right)
Multiply both sides of the equation by 24, the least common multiple of 8,6,2,12.
3\times 7x-4\left(x-5\right)=12\left(x-4\right)-2\left(4x+7\right)
Combine 2x and 5x to get 7x.
21x-4\left(x-5\right)=12\left(x-4\right)-2\left(4x+7\right)
Multiply 3 and 7 to get 21.
21x-4x+20=12\left(x-4\right)-2\left(4x+7\right)
Use the distributive property to multiply -4 by x-5.
17x+20=12\left(x-4\right)-2\left(4x+7\right)
Combine 21x and -4x to get 17x.
17x+20=12x-48-2\left(4x+7\right)
Use the distributive property to multiply 12 by x-4.
17x+20=12x-48-8x-14
Use the distributive property to multiply -2 by 4x+7.
17x+20=4x-48-14
Combine 12x and -8x to get 4x.
17x+20=4x-62
Subtract 14 from -48 to get -62.
17x+20-4x=-62
Subtract 4x from both sides.
13x+20=-62
Combine 17x and -4x to get 13x.
13x=-62-20
Subtract 20 from both sides.
13x=-82
Subtract 20 from -62 to get -82.
x=\frac{-82}{13}
Divide both sides by 13.
x=-\frac{82}{13}
Fraction \frac{-82}{13} can be rewritten as -\frac{82}{13} by extracting the negative sign.
