Answer:
39
Step-by-step explanation:
In order to solve this you have to fond r.
In 3r=18 you divide the 3 from both sides to isolate the variable.
18÷3=6 so you are left with r=6
So r is 6.
Plug that into 6r+3
6(6)+3
6×6=36
36+3=39
3r = 18 (given in the question)
r = 18 / 3
r = 6
substituting r = 6 in the equation we get:
= 6r + 3
= 6 (6) + 3 (by multiplying 6 (6) u will get 36)
= 36 + 3 = 39
Hope it helps
All the best!
