Answer:
B. 2
Step-by-step explanation:
[tex]9r-2=16[/tex]
First, add 2 to 2 and 16.
[tex]-2 + 2 = 0[/tex] (cancels itself out)
[tex]16 + 2 = 18.[/tex]
Now we are left with:
[tex]9r = 18[/tex]
Lastly, divide the coefficient from the answer.
[tex]18/9=2[/tex]
Therefore, the value of 'r' is 2.
Here is an attachment to make this clearer.
