Answer:x=4 y=3
Explanation:
5x-4y=8.............(1)
2x+y=11................(11)
From (11) y=11-2x
Substitute y=11-2x in 5x-4y=8
5x-4y=8
5x-4(11-2x)=8
Open bracket
5x-44+8x=8
Collect like terms
5x+8x=8+44
13x=52
Divide both sides by 13
13x/13=52/13
x=4
Substitute x=4 in 2x+y=11
2(4)+y=11
8+y=11
Collect like terms
y=11-8
y=3
