Question

solve 5x+y=3
2x-3y=25 by elimination techniche

Answer 1

5x+y=3 multiply this equation by 3 so we can eliminate the -3y below this gives us:

15x+3y=9
2x-3y=25
-----------
= 17x+0y=34

==> x=34/17=2

Insert x=2 into any of the two original equations and you get:
equation 1: 5*2+y=3 <==> y=-7
equation 2: 2*2 -3y=25 <==> -3y=21 <==> y=-7

So you get the answer x=2 and y=-7

You can check that the values of x and y are correct by inserting them to any of the two equations.

Hope this helps!?!
