Question

If 3r = 18, what is the value of 6r + 3

Answer 1

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

Answer 2

Answer:

39

Step-by-step explanation:

     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
