Answer:
x=3 y=2
Step-by-step explanation:
2x-y=4
7x+3y=27
Multiply the first equation by 3
3(2x-y)=4*3
6x - 3y+12
Add this to the second equation to eliminate y
6x -3y = 12
7x+3y=27
---------------------
13x +0y = 39
Divide each side by 13
13x/13 = 39/13
x = 3
Now find y
2x-y =4
2(3) -y = 4
6-y=4
Subtract 6 from each side
6-y-6 = 4-6
-y = -2
y=2
