-\left(3x-88\right)=35x
Multiply both sides of the equation by 7.
-3x-\left(-88\right)=35x
To find the opposite of 3x-88, find the opposite of each term.
-3x+88=35x
The opposite of -88 is 88.
-3x+88-35x=0
Subtract 35x from both sides.
-38x+88=0
Combine -3x and -35x to get -38x.
-38x=-88
Subtract 88 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-88}{-38}
Divide both sides by -38.
x=\frac{44}{19}
Reduce the fraction \frac{-88}{-38} to lowest terms by extracting and canceling out -2.
