2x - 4y = 8 and 3x + y = 36

Answer:x=12 and y=4

Step-by-step explanation:

To find 2x-4y=8 and 3x+y=36

Solve simultaneously

Using elimination method

6x-12y=16

6x+2y=72

We are going to eliminate x

Then we are going have

-14y=-56

Divide through by - 14

Then our answer for Y is;

Y=4

To get x, substitute for y in equation 1

2x-4 (4) = 8

2x=8+16

2x=24

Then our answer for x is

x=12
