Question

Solve the equation 9r – 2 = 16 for r. A. 1 B. 2 C. 4 D. 6

Answer 1

Answer:

Its B. two

Step-by-step explanation:

9·2 =18 and 18-2 =16

Answer 2

Answer:

B. 2

Step-by-step explanation:

$9r-2=16$

First, add 2 to 2 and 16.

$-2 + 2 = 0$ (cancels itself out)

$16 + 2 = 18.$

Now we are left with:

$9r = 18$

Lastly, divide the coefficient from the answer.

$18/9=2$

Therefore, the value of 'r' is 2.
