| Zombie man how do I do this X+Y=11 and 3x -y=5 ? What is a system? You can't add and subtract lettars ? This is DUMB! | |
 | |  |
|
 |
 | |  |
| It isn't hard at all i promise! We are going to use the elimination way. First you got to get your problems right over top of each other! But got to make sure you can get x or y to cancel out! | |

| Oh like negative y and postive Y | |
 | |  |
|
 |
 | |  |
| Yes, there you go!.............. X+Y=11. 3x-Y=5 Then you add whats left so you would have 4x=16. Divide by 4 and get x=4. Then put x back in 4+Y=11 subtract 4 from 11 and there is Y. (4,7) | |
