Solve for x and y 3x+y = 5 x-2y=4 Solve for x and y 3x+y = 5 x-2y=4

3x + y =
5..........(1)

x - 2y = 4 ..........(2)

First let us use
the elimination method.

Let us multiply (1) by 2 and add to (2):

==> 7x = 14

==> x = 2

Now using the
substitution method substitute x velue in (2)

x-2y = 4

2 -
2y = 4

2-4 = 2y

-2 = 2y

==> y=
-1

The solution is:

x= 2   and y=
-1
