Step-by-step explanation:
6x+3y=54
- 2x+y=18
I'm going to be using the elimination method cause it seems easiest here. so for the elimination method u choose a variable to eliminate I chose y u could do x too if u want to. so first step would be to multiply the second equation by 3. 6x+3y=54
so now u just have to eliminate
6x+3y=54
- 6x+3y=54
because these cancel out the answer would be an infinite solution
