Answer:
(0,-2), (5,0) and (10,2).
Step-by-step explanation:
Given equation is
.
Now we need to find 3 pairs of solutions in (x,y) form for the given equation.
As
is a linear equation so we are free to pick any number for x like x=0, 5, 10
Plug x=0 into
, we get:
![2(0)-5y=10](https://tex.z-dn.net/?f=2%280%29-5y%3D10)
![0-5y=10](https://tex.z-dn.net/?f=0-5y%3D10)
![-5y=10](https://tex.z-dn.net/?f=-5y%3D10)
![y=\frac{10}{-5}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B10%7D%7B-5%7D)
![y=-2](https://tex.z-dn.net/?f=y%3D-2)
Hence first solution is (0,-2)
We can repeat same process with x=5 and 10 to get the other solutions.
Hence final answer is (0,-2), (5,0) and (10,2).
