Answer:

X = 4.27 and Y = -0.92

Step-by-step explanation:

2.5x + 3y =8. eq1

4x-y=18. eq2 (multiply by 3)

12x - 3y=54

add both

we get. 14.5x =62

x = 62/14.5

x= 4.27

4x-y=18

put X= 4.27

we get 4.27x 4 - y =18

- y= 18- 17.08

-y = 0.92

y = - 0.92

Note: Sorry, I thought it was 2.5x instead of 5x
