-3\left(7x-\frac{1}{3}\right)-4\left(5x-\frac{3}{4}\right)=-2\left(2x-1,5\right)+6\left(5x-\frac{1\times 6+1}{6}\right)
Multiply both sides of the equation by 12, the least common multiple of -4;3;-6;2.
-21x-3\left(-\frac{1}{3}\right)-4\left(5x-\frac{3}{4}\right)=-2\left(2x-1,5\right)+6\left(5x-\frac{1\times 6+1}{6}\right)
Use the distributive property to multiply -3 by 7x-\frac{1}{3}.
-21x+1-4\left(5x-\frac{3}{4}\right)=-2\left(2x-1,5\right)+6\left(5x-\frac{1\times 6+1}{6}\right)
Multiply -3 times -\frac{1}{3}.
-21x+1-20x-4\left(-\frac{3}{4}\right)=-2\left(2x-1,5\right)+6\left(5x-\frac{1\times 6+1}{6}\right)
Use the distributive property to multiply -4 by 5x-\frac{3}{4}.
-21x+1-20x+3=-2\left(2x-1,5\right)+6\left(5x-\frac{1\times 6+1}{6}\right)
Multiply -4 times -\frac{3}{4}.
-41x+1+3=-2\left(2x-1,5\right)+6\left(5x-\frac{1\times 6+1}{6}\right)
Combine -21x and -20x to get -41x.
-41x+4=-2\left(2x-1,5\right)+6\left(5x-\frac{1\times 6+1}{6}\right)
Add 1 and 3 to get 4.
-41x+4=-4x+3+6\left(5x-\frac{1\times 6+1}{6}\right)
Use the distributive property to multiply -2 by 2x-1,5.
-41x+4=-4x+3+6\left(5x-\frac{6+1}{6}\right)
Multiply 1 and 6 to get 6.
-41x+4=-4x+3+6\left(5x-\frac{7}{6}\right)
Add 6 and 1 to get 7.
-41x+4=-4x+3+30x+6\left(-\frac{7}{6}\right)
Use the distributive property to multiply 6 by 5x-\frac{7}{6}.
-41x+4=-4x+3+30x-7
Cancel out 6 and 6.
-41x+4=26x+3-7
Combine -4x and 30x to get 26x.
-41x+4=26x-4
Subtract 7 from 3 to get -4.
-41x+4-26x=-4
Subtract 26x from both sides.
-67x+4=-4
Combine -41x and -26x to get -67x.
-67x=-4-4
Subtract 4 from both sides.
-67x=-8
Subtract 4 from -4 to get -8.
x=\frac{-8}{-67}
Divide both sides by -67.
x=\frac{8}{67}
Fraction \frac{-8}{-67} can be simplified to \frac{8}{67} by removing the negative sign from both the numerator and the denominator.
