X would be 0 while Y would be 4
3x+y=4
-(2x+y=4)
----------------
x=0
Plug in x to any of those two equations in their original form
3(0)+y=4
0 + y = 4
y = 4
Where x is the length of the first piece

so the first piece is 3 inches, the second is 6 inches and the third is 19 inches
The property shown in the following equation is 9 beacause simply we know 9=1 +8 so its easy
