Answer:
C
Step-by-step explanation:
On the left, we have 3 positive x bars and 8 1s.
Hence, the left can be represented by the following expression:
On the right, we have 4 positive x bars and 6 1s.
Hence, the right can be represented by the following expression:
The two are equivalent. Therefore:
Solve for x. Subtract 6 from both sides:
Subtract 3x from both sides:
Flip:
Hence, our answer is C.
