8\times 4\left(2x-1\right)-\left(7x+1\right)=3\times 3\left(5x-1\right)+24x
Multiply both sides of the equation by 24, the least common multiple of 3,24,8.
32\left(2x-1\right)-\left(7x+1\right)=3\times 3\left(5x-1\right)+24x
Multiply 8 and 4 to get 32.
64x-32-\left(7x+1\right)=3\times 3\left(5x-1\right)+24x
Use the distributive property to multiply 32 by 2x-1.
64x-32-7x-1=3\times 3\left(5x-1\right)+24x
To find the opposite of 7x+1, find the opposite of each term.
57x-32-1=3\times 3\left(5x-1\right)+24x
Combine 64x and -7x to get 57x.
57x-33=3\times 3\left(5x-1\right)+24x
Subtract 1 from -32 to get -33.
57x-33=9\left(5x-1\right)+24x
Multiply 3 and 3 to get 9.
57x-33=45x-9+24x
Use the distributive property to multiply 9 by 5x-1.
57x-33=69x-9
Combine 45x and 24x to get 69x.
57x-33-69x=-9
Subtract 69x from both sides.
-12x-33=-9
Combine 57x and -69x to get -12x.
-12x=-9+33
Add 33 to both sides.
-12x=24
Add -9 and 33 to get 24.
x=\frac{24}{-12}
Divide both sides by -12.
x=-2
Divide 24 by -12 to get -2.
