3x%2F4-7=8

Step 1. Multiply 4 to both sides of the equation to get rid of denominator

4%2A%283x%2F4-7%29=4%2A8

3x-28=32

Step 2. Add 28 to both sides to get x-terms on left side and numbers on right side of equation.

3x-28%2B28=32%2B28

3x=60

Step 3. Divide 18 to both sides of the equation to get x.

3x%2F3=60%2F3

x=20

Step 4. So answer is x=20.

I hope the above steps and explanation were helpful.
