​

Answer 1

kelvin is right lol

Explanation:

Answer 2

C

Explanation:

On the left, we have 3 positive x bars and 8 1s.

Hence, the left can be represented by the following expression:

`3x+8`

On the right, we have 4 positive x bars and 6 1s.

Hence, the right can be represented by the following expression:

`4x+6`

The two are equivalent. Therefore:

`3x+8=4x+6`

Solve for x. Subtract 6 from both sides:

`3x+2=4x`

Subtract 3x from both sides:

`2=x`

Flip:

`x=2`

Hence, our answer is C.
