Answer:

B.
x = (9)/(2)

Explanation:

On our left, we have 7 "x's" and 7 "1's". Let this be 7x + 7.

On our right, we have 5 "x's" and 16 "1's". Let this be 5x + 16.

We would have the equation:


7x + 7 = 5x + 16

Solve for x. Collect like terms.


7x - 5x = 16 - 7


2x = 9

Divide both sides by 2


(2x)/(2) = (9)/(2)


x = (9)/(2)
