30\left(5x-3\right)-15\left(2x-1\right)-70\left(3x-4\right)=10\left(2x-3\right)+21\left(3x-4\right)
Multiply both sides of the equation by 210, the least common multiple of 7,14,3,21,10.
150x-90-15\left(2x-1\right)-70\left(3x-4\right)=10\left(2x-3\right)+21\left(3x-4\right)
Use the distributive property to multiply 30 by 5x-3.
150x-90-30x+15-70\left(3x-4\right)=10\left(2x-3\right)+21\left(3x-4\right)
Use the distributive property to multiply -15 by 2x-1.
120x-90+15-70\left(3x-4\right)=10\left(2x-3\right)+21\left(3x-4\right)
Combine 150x and -30x to get 120x.
120x-75-70\left(3x-4\right)=10\left(2x-3\right)+21\left(3x-4\right)
Add -90 and 15 to get -75.
120x-75-210x+280=10\left(2x-3\right)+21\left(3x-4\right)
Use the distributive property to multiply -70 by 3x-4.
-90x-75+280=10\left(2x-3\right)+21\left(3x-4\right)
Combine 120x and -210x to get -90x.
-90x+205=10\left(2x-3\right)+21\left(3x-4\right)
Add -75 and 280 to get 205.
-90x+205=20x-30+21\left(3x-4\right)
Use the distributive property to multiply 10 by 2x-3.
-90x+205=20x-30+63x-84
Use the distributive property to multiply 21 by 3x-4.
-90x+205=83x-30-84
Combine 20x and 63x to get 83x.
-90x+205=83x-114
Subtract 84 from -30 to get -114.
-90x+205-83x=-114
Subtract 83x from both sides.
-173x+205=-114
Combine -90x and -83x to get -173x.
-173x=-114-205
Subtract 205 from both sides.
-173x=-319
Subtract 205 from -114 to get -319.
x=\frac{-319}{-173}
Divide both sides by -173.
x=\frac{319}{173}
Fraction \frac{-319}{-173} can be simplified to \frac{319}{173} by removing the negative sign from both the numerator and the denominator.
