Question

2x – y = 5
3x – 2y = 12

Answer 1

2x – y = 5

– y = -2x + 5

y = 2x - 5

--------------------

3x – 2y = 12


3x – 2(2x - 5) = 12


3x-4x+10=12


-x+10=12


-x=12-10


-x=2


x=2/(-1)


x=-2

--------------------------

y = 2x - 5


y = 2(-2) - 5


y = -4 - 5


y = -9


So the solutions are x = -2 and y = -9
