i have no clue how to solve

you probably have a square root sign in there somewhere, but
do you mean
√(9x+67) = x+5 or
√(9x) + 67 = x+5 ?
hint: square both sides of the equation.

If I asked you to solve
√x = 5
could you solve that?
Sure. You'd just say
x = 5^2 = 25
same thing here
√9x+67 = x+5
9x+67 = (x+5)^2
expand the right side, collect terms, and solve the quadratic.
If that mystifies you, you're in big trouble. See someone in person for help.
