Solve for x and y using  x + 2y = 8 and 3x + 4y = 16  

Expert Answers

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

x+ 2y = 8........(1)

3x + 4y = 16........(2)

Let us use the elimination method to solve:

We'll multiply (1) by -2 and add to (2):

-2x - 4y = -16

3x + 4y = 16

==> Now add both equations:

==> x = 0

Now to find y , we will substitute with (1):

x + 2y = 8

0 + 2y = 8

==> 2y= 8

==> y= 4

Then, the solution is:

(x, y) = ( 0, 4)
