Elimination Method Part 2

Question 1: Given the system of equations 4x+2y=10 and -2x-3y=1, which equation should we multiple to eliminate a variable, and what should we multiply it by?

Question 2: True or False: Sometimes using the elimination method we need to multiply both equations by a constant.

Question 3: Solve the system of equations using elimination -5x-20y=-15 and 2x+8y=6

Question 4: Solve the system using elimination 2x-y=-3 and -10x-7y=3

Question 5: Solve the system using elimination -4x-2y=14 and 7y=-25+10x
