x-5+x-7=4\left(x+6\right)-4\left(x+4\right)-2\left(x+6\right)
Multiply both sides of the equation by 8, the least common multiple of 8,2,4.
2x-5-7=4\left(x+6\right)-4\left(x+4\right)-2\left(x+6\right)
Combine x and x to get 2x.
2x-12=4\left(x+6\right)-4\left(x+4\right)-2\left(x+6\right)
Subtract 7 from -5 to get -12.
2x-12=4x+24-4\left(x+4\right)-2\left(x+6\right)
Use the distributive property to multiply 4 by x+6.
2x-12=4x+24-4x-16-2\left(x+6\right)
Use the distributive property to multiply -4 by x+4.
2x-12=24-16-2\left(x+6\right)
Combine 4x and -4x to get 0.
2x-12=8-2\left(x+6\right)
Subtract 16 from 24 to get 8.
2x-12=8-2x-12
Use the distributive property to multiply -2 by x+6.
2x-12=-4-2x
Subtract 12 from 8 to get -4.
2x-12+2x=-4
Add 2x to both sides.
4x-12=-4
Combine 2x and 2x to get 4x.
4x=-4+12
Add 12 to both sides.
4x=8
Add -4 and 12 to get 8.
x=\frac{8}{4}
Divide both sides by 4.
x=2
Divide 8 by 4 to get 2.
