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
