8\left(x-1\right)-3\left(5x+2\right)=4\left(2x-3\right)+6\left(x-3\right)
Multiply both sides of the equation by 24, the least common multiple of 3,8,6,4.
8x-8-3\left(5x+2\right)=4\left(2x-3\right)+6\left(x-3\right)
Use the distributive property to multiply 8 by x-1.
8x-8-15x-6=4\left(2x-3\right)+6\left(x-3\right)
Use the distributive property to multiply -3 by 5x+2.
-7x-8-6=4\left(2x-3\right)+6\left(x-3\right)
Combine 8x and -15x to get -7x.
-7x-14=4\left(2x-3\right)+6\left(x-3\right)
Subtract 6 from -8 to get -14.
-7x-14=8x-12+6\left(x-3\right)
Use the distributive property to multiply 4 by 2x-3.
-7x-14=8x-12+6x-18
Use the distributive property to multiply 6 by x-3.
-7x-14=14x-12-18
Combine 8x and 6x to get 14x.
-7x-14=14x-30
Subtract 18 from -12 to get -30.
-7x-14-14x=-30
Subtract 14x from both sides.
-21x-14=-30
Combine -7x and -14x to get -21x.
-21x=-30+14
Add 14 to both sides.
-21x=-16
Add -30 and 14 to get -16.
x=\frac{-16}{-21}
Divide both sides by -21.
x=\frac{16}{21}
Fraction \frac{-16}{-21} can be simplified to \frac{16}{21} by removing the negative sign from both the numerator and the denominator.
