x-6%2F7%2B4=15 Start with the given equation.


7%28x-6%2Fcross%287%29%2B4%29=7%2815%29 Multiply both sides by the LCD 7 to clear any fractions.


7x-6%2B28=105 Distribute and multiply.


7x%2B22=105 Combine like terms on the left side.


7x=105-22 Subtract 22 from both sides.


7x=83 Combine like terms on the right side.


x=%2883%29%2F%287%29 Divide both sides by 7 to isolate x.

Answer:

So the solution is x=83%2F7 which approximates to x=11.857.
