The transformation is a reflection on the y-axis.
If we take the y-axis as the mirror line as shown in the diagram below, we can see that the distance of vertices A, B, and C to the mirror line are equals to the distance of vertices A', B' and C' to the mirror line.
Answer:
-13 + 5*n-1 I think
Step-by-step explanation:
Distribute: 3x+6+4=5x+7

Divide by 2: x=3/2
x=3/2
