let the third side=y
-5-3x+5x+9+3x+12+y=6x+8x
5x+16+y=6x+8x
y=9x-16
Measure of third side = 9x-16
-5-3x+5x+9+3x+12+y=6x+8x
5x+16+y=6x+8x
y=9x-16
Measure of third side = 9x-16

It came from your question , doesn't it?
ohh
sorry i am weak in maths
just do more practice and it will be better soon :)
in third line how did 16 came
-5-3x+5x+9+3x+12+y=6x+8x
To see it easily, categorize it first by seperate unknown and numerical
(-5+9+12)+ (-3x+5x+3x) +y =6x+8x
16 +5x + y = 6x + 8x
