Answer:
Exactly one solution
Step-by-step explanation:
4x -2y = 8
2x +y = 2
Multiply the second equation by 2
4x +2y = 4
Add the two equations together
4x -2y = 8
4x +2y = 4
-------------------
8x = 12
x = 12/8
We know there will be one solution
If there are that many things missing then go left to right; 5+1 then multiply the sum by ten
5+1=6
6x10=60
