what would you need to multiply by in order to solve this system of equations using the linear combination (elimination) method?
−2x+3y=8
5x+4y=10
multiply the 1st equation by 3 and leave the 2nd equation alone. this will eliminate the x's when you add the two new equations together.
multiply the 1st equation by 5 and multiply the 2nd equation by 2. this will eliminate the x's when you add the two new equations together.
multiply the 1st equation by 4 and multiply the 2nd equation by 2. this will eliminate the y's when you add the two new equations together.
