Answer:
6x - 1
Step-by-step explanation:
Okay this is basically polynomial algebra:
1. Add the value of the lengths already given.
like terms: 3x + x = 4x, -4 + 2 = -2. Now you're left with, 4x - 2.
2. Find the difference between the perimeter and the sum of the lengths.
(10x -3) + (4x + 2) = 6x - 1
-6x + 2y = 8
isolate the y
first add 6x to both sides
2y = 6x + 8
then divide everything by 2 to isolate the y
y = 3x + 4
Hope this helps
