Answer:
x=1/2
y=7
Step-by-step explanation:
2x − y + 6 = 0
4x + y − 9 = 0
Solve the second equation for y
y = 9-4x
Substitute this into the first equation
2x - (9-4x) +6 = 0
Distribute the minus sign
2x -9 +4x +6 =0
6x -3 =0
Add 3 to each side
6x =3
Divide by 6
6x/6 = 3/6
x =1/2
Now find y
y = 9-4x
y = 9 -4(1/2)
y = 9 - 2
y =7
