Question

Need to solve for X and Y:
3x - y = -5
x + 2y = 3

Answer 1

Multiply the 2nd line by -3 and cancel the the x's to solve for y

Answer 2

once you have y you can rearrange for solve for x

Answer 3

Ooooo, I didn't even think of that!

Answer 4

multiply equation 1 by 2.. 6x -2y = -10

and add it with eqnt 2.. x + 2y = 3

there fore you get is; 7x = -7

therefore x = -1 , substitute in any of eqtn.. solve y ..

Answer 5

Ok, so your cancelling the Y's rather than the X's, right Ganpat?

Answer 6

Yeah he is, he's solving for x first, then y.

Answer 7

Got it! OK, thx!

Answer 8

its either way.. for cancelling x, multiply equation, by 2.. and then subtract both..
