5\left(x+7\right)-4\left(x+1\right)=2\left(x+1\right)-10\left(x+1\right)
Multiply both sides of the equation by 20, the least common multiple of 4,5,10,2.
5x+35-4\left(x+1\right)=2\left(x+1\right)-10\left(x+1\right)
Use the distributive property to multiply 5 by x+7.
5x+35-4x-4=2\left(x+1\right)-10\left(x+1\right)
Use the distributive property to multiply -4 by x+1.
x+35-4=2\left(x+1\right)-10\left(x+1\right)
Combine 5x and -4x to get x.
x+31=2\left(x+1\right)-10\left(x+1\right)
Subtract 4 from 35 to get 31.
x+31=2x+2-10\left(x+1\right)
Use the distributive property to multiply 2 by x+1.
x+31=2x+2-10x-10
Use the distributive property to multiply -10 by x+1.
x+31=-8x+2-10
Combine 2x and -10x to get -8x.
x+31=-8x-8
Subtract 10 from 2 to get -8.
x+31+8x=-8
Add 8x to both sides.
9x+31=-8
Combine x and 8x to get 9x.
9x=-8-31
Subtract 31 from both sides.
9x=-39
Subtract 31 from -8 to get -39.
x=\frac{-39}{9}
Divide both sides by 9.
x=-\frac{13}{3}
Reduce the fraction \frac{-39}{9} to lowest terms by extracting and canceling out 3.
