In order to solve the following system of equations by subtraction, which of the following could you do before subtracting the e quations so that one variable will be eliminated when you subtract them? 4x-2y=7 and 3x-3y=15
2 answers:
I can't see the options, but you would need to multiply (4x - 2y = 7) by 3, and (3x - 3y = 15) by 4 so that you get 12x in both equations. Then when you subtract, you eliminate 12x. I hope this helps!
Answer:multiply top by 3 and bottom by 4
