What is x of 3/4 (x+3) = 9

What is x of 3/4 x + 9/4 = 9

3/4 (x+3) = 9

3/4x + 2.25 = 9

3/4x = 6.75

x=9

First, you make 9 into a fraction which would become 36/4

then, subtract 9/4 from both sides so that would give you 3/4x = 27/4

then divide each side by 3/4 (same thing as multiply by its reciprocal) and that would give you x=9
