No math is my weakest subject

Answer 3

ok then
5x + 2y = 18
2x + 2y = 30
-------------
just change one of any equation into all negatives

ex.
2x + 5y = 4
6x + 5y = 7
-----------
2x + 5y = 4
-1(6x + 5y = 7)

so can you try it by your self like how i did with the example?

Answer 4

because i have to teach you not give you answers

Answer 6

5x + 2y = 18
2x + 2y = 30
-------------
5x + 2y = 18
-1(2x + 2y = 30)
-------------
5x + 2y = 18
-2x - 2y = -30
-------------
x = ?
