Answer:

B. [tex] x = \frac{9}{2} [/tex]

Step-by-step 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:

[tex] 7x + 7 = 5x + 16 [/tex]

Solve for x. Collect like terms.

[tex] 7x - 5x = 16 - 7 [/tex]

[tex] 2x = 9 [/tex]

Divide both sides by 2

[tex] \frac{2x}{2} = \frac{9}{2} [/tex]

[tex] x = \frac{9}{2} [/tex]
