11\left(5\left(x+1\right)-4\right)=8\left(7x-1\right)
Multiply both sides of the equation by 88, the least common multiple of 8,11.
11\left(5x+5-4\right)=8\left(7x-1\right)
Use the distributive property to multiply 5 by x+1.
11\left(5x+1\right)=8\left(7x-1\right)
Subtract 4 from 5 to get 1.
55x+11=8\left(7x-1\right)
Use the distributive property to multiply 11 by 5x+1.
55x+11=56x-8
Use the distributive property to multiply 8 by 7x-1.
55x+11-56x=-8
Subtract 56x from both sides.
-x+11=-8
Combine 55x and -56x to get -x.
-x=-8-11
Subtract 11 from both sides.
-x=-19
Subtract 11 from -8 to get -19.
x=19
Multiply both sides by -1.
