2x-3y = 8       x+2y=3    solve x and y

Expert Answers

An illustration of the letter 'A' in a speech bubbles

2x-3y =8......(1)

x+2y =3.......(2)

We will use the elimination method to solve:

First, multiply (2) by -2 and add to (1):

-7y = 2

==> y= -2/7

Now substitute y= -2/7 in (2):

x+ 2y= 3

x+ 2(-2/7) = 3

x -4/7= 3

Move -4/7  to the right side:

x= 3+ 4/7

x= 21/7  + 4/7 = 25/7

x= 25/7
