Answer:

8x+8

Explanation:

perimeter = lengths of all sides added up

we want all sides to add up to 6x + 4

so far, we have 2x-7 and -4x + 3

side 1 + side 2 + side 3 = perimeter = 6x + 4

2x - 7 + (-4x + 3) + side 3 = 6x + 4

-2x -4 + side 3 = 6x + 4

add (2x+4) to both sides to isolate side 3

side 3 = 8x + 8
