7\left(3x+8\right)-5\left(9x-9\right)=5\left(31x-4\right)+2\left(4x-1\right)
Multiply both sides of the equation by 70, the least common multiple of 10,14,35.
21x+56-5\left(9x-9\right)=5\left(31x-4\right)+2\left(4x-1\right)
Use the distributive property to multiply 7 by 3x+8.
21x+56-45x+45=5\left(31x-4\right)+2\left(4x-1\right)
Use the distributive property to multiply -5 by 9x-9.
-24x+56+45=5\left(31x-4\right)+2\left(4x-1\right)
Combine 21x and -45x to get -24x.
-24x+101=5\left(31x-4\right)+2\left(4x-1\right)
Add 56 and 45 to get 101.
-24x+101=155x-20+2\left(4x-1\right)
Use the distributive property to multiply 5 by 31x-4.
-24x+101=155x-20+8x-2
Use the distributive property to multiply 2 by 4x-1.
-24x+101=163x-20-2
Combine 155x and 8x to get 163x.
-24x+101=163x-22
Subtract 2 from -20 to get -22.
-24x+101-163x=-22
Subtract 163x from both sides.
-187x+101=-22
Combine -24x and -163x to get -187x.
-187x=-22-101
Subtract 101 from both sides.
-187x=-123
Subtract 101 from -22 to get -123.
x=\frac{-123}{-187}
Divide both sides by -187.
x=\frac{123}{187}
Fraction \frac{-123}{-187} can be simplified to \frac{123}{187} by removing the negative sign from both the numerator and the denominator.
