Answer:eliminationStep-by-step explanation:5x + 4y = -143x + 6y = 6if you want to substitute something into another equation, you would want to have an x= # or y= #.if you want to eliminate something, you would see what you can eliminate.I suggest you eliminate the x's or the y's than you to substitute because elimination will go a little faster for you.
