Answer 2

5x -1y =6 am i right meverett

Answer 3

i havent done one that are subtration

Answer 4

@sunset almost

Take

7x - 3y = 4
2x - 4y = 1

We need to make the y's opposite so multiple the first equation by 4

28x - 12y = 16

and the second equation by 3

6x - 12y = 3

and take these two equations


28x - 12y = 16
6x - 12y = 3

and subtraction

22x = 13

and so on...
