3864-3x+168=7x
Multiply both sides of the equation by 21, the least common multiple of 7,3.
4032-3x=7x
Add 3864 and 168 to get 4032.
4032-3x-7x=0
Subtract 7x from both sides.
4032-10x=0
Combine -3x and -7x to get -10x.
-10x=-4032
Subtract 4032 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-4032}{-10}
Divide both sides by -10.
x=\frac{2016}{5}
Reduce the fraction \frac{-4032}{-10} to lowest terms by extracting and canceling out -2.
