On this problem my answer was 7 was I wrong?
Because when I check my work and put in 7 it equals out.
3(7)-5+2(7)-3+15-(7)=35
21-5+14-3+15-7=35
16+11+8=35

(3x - 5) + (15 - x) + (2x - 3) = 35

3x - 5 + 15 - x + 2x - 3 = 35

3x - x + 2x - 5 + 15 - 3 = 35

4x + 7 = 35

4x = 28

x = or units

Side that's "3x - 5" = 3(7) - 5 = 21 - 5 = units.

Side that's "15 - x" = 15 - 7 = units.

Side that's "2x - 3" = 2(7) - 3 = 14 - 3 = units.

-----------
Check
-----------
Perimeter = 16 + 8 + 11 = 35 units
