Hi, would it be possible for a bit of guidance on the following question?
I need to find the value of x, here is what I have done so far,
x/3 +15 = 3 (x11)
Mulitpiled each side by 3 (the denominator)
3(x/3 + 15) = 9 (x11)
Multilpied out the brackets
x + 45 = 9x99
Subtract x ?
45 = 8x99
Now I get a little stuck, I am pretty sure x =18 but cannot get this with the final steps of the calculation.
Any help would be very much appreciated.

You were doing fine. Now add 99 to both sides.
8x = 144
Then divide both sides by 8
x = 18
