%282%2F3%29x-1=x%2B7 Start with the given equation.


3%28%282%2Fcross%283%29%29x-1%29=3%28x%2B7%29 Multiply both sides by the LCD 3 to clear any fractions.


2x-3=3x%2B21 Distribute and multiply.


2x=3x%2B21%2B3 Add 3 to both sides.


2x-3x=21%2B3 Subtract 3x from both sides.


-x=21%2B3 Combine like terms on the left side.


-x=24 Combine like terms on the right side.


x=%2824%29%2F%28-1%29 Divide both sides by -1 to isolate x.


x=-24 Reduce.
