Question 245293: Solve using the elimination method
-5r + 4s = 8
15r - 12s = 24

You can put this solution on YOUR website!
-5r+4s=8
15r-12s=24
First you need to multiply the whole equation so you can eliminate a variable.
3(-5r+4s=8)
-15r+12s=24
Then subtract or add to eliminate the variable.
In this case just add.
-15r+12s=24
15r-12s=24
Both variables cancel in this case and you get:
0=48
When you get this type of answer, it means there is no solution.
So no solution
