Answer:

x=1, y=2

Explanation:

1) 8x+3y=14 Original system of linear 2d equations

2x+y=4

2) 8x+3y=14

-4 (2x+y) =-4(4) Multiply second equation by negative four.

3) 8x+3y=14

+ -8x-4y=-16 Add equations, eliminating x terms

4) -y=-2

y=2 solve for y

5) 8x+3(2)=14 Substitute solution for y to solve for x

8x=14-6

8x=8

x=1
