The supplement of 61 degree is 119 degrees
180-61=119
1) Create a number line with that can fit all your numbers
-----|------|-------|-----|---
1 2 3 4
2) then put an x over the number that you have. If you have the number more than once put how many numbers there are Example: 1,2,3
x x x x x
---|--------|------|------- x x x
1 2 3 --------|-------|-------| <- For more than one of the same number 1 2 3 Example: 1,1,2,3,3
X-y=1
x+y=3
You see the y's can cancel out. So add it together and you have:
2x=4
x=2
Now that you have x, plug it in to one of the equations to find y.
I will plug it into the first one.
(2)-y=1
-y=-1
y=1
