Answer: x = 2 Hope this helps, please consider making me Brainliest.
Step-by-step explanation:
Let's solve for x:
4x + 6 + 2x = 18
4x + 2x = 12
6x = 12
x = 2

Recall the logarithm rules :
a^y = x  is the same as log_a x = y
In this case, 
a = 18
y = r - 10
x = 93
So,
18^ (r-10) = 93
is the same as
log_18  93 = r - 10
Solve for r to get :
10 + log_18  93 = r
