1. Solve the system using the substration method 3x - 4y = -5 -x + 2y = 3 2.Solve the system using the Linear combination method

3x-4y=9
-3x+2y=-9

3.Solve the system using the Linear combination method

x+6y=2
5x+4y=36

4.Solve the system using the Linear combination method

5x-2y=6
-3x+y=2

Please help ASAP

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.
