7\left(2x+1\right)-21\left(5x-2\right)=21x-273
Multiply both sides of the equation by 21, the least common multiple of 3,7.
14x+7-21\left(5x-2\right)=21x-273
Use the distributive property to multiply 7 by 2x+1.
14x+7-105x+42=21x-273
Use the distributive property to multiply -21 by 5x-2.
-91x+7+42=21x-273
Combine 14x and -105x to get -91x.
-91x+49=21x-273
Add 7 and 42 to get 49.
-91x+49-21x=-273
Subtract 21x from both sides.
-112x+49=-273
Combine -91x and -21x to get -112x.
-112x=-273-49
Subtract 49 from both sides.
-112x=-322
Subtract 49 from -273 to get -322.
x=\frac{-322}{-112}
Divide both sides by -112.
x=\frac{23}{8}
Reduce the fraction \frac{-322}{-112} to lowest terms by extracting and canceling out -14.
