Answer 6

let me give you an example
5x + 3y = 18 (1)
2x - 6y = 30 (2)

pick what you want to solve first, let us say y. multiply the first equation by 2 so it becomes
10x + 6y = 36 which means our y can be canceled
2x - 6y = 30
----------------
12x = 66

divide both sides by 12
x = 11/5

use the value of x and plug it in to one of the original equation to solve for y
2(11/5) - 6y = 30

22/5 - 6y = 30
-6y = 30- 22/5
simplify
