What would you need to multiply by in order to solve this system of equations using the linear combination (elimination) method?
{6x−2y=4
7x+5y=3
Multiply the 1st equation by 3 and leave the 2nd equation alone. This will eliminate the y's when you add the two new equations together.
Multiply the 2nd equation by -6 and leave the 1st equation alone. This will eliminate the x's when you add the two new equations together.
Multiply the 1st equation by 7 and multiply the 2nd equation by 4. 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 y's when you add the two new equations together.
