I am not sure how your teacher wanted you to estimate the answer but I solved it for you. Hopefully this helps.
Step-by-step explanation:
7x-y=7
x+2y=6
14x-2y=14
x+2y=6
add both equations
15x=20
x=20/15
x=4/3
x+2y=6
4/3+2y=6
2y=6-4/3
2y=18/3 -4/3
2y=14/3
divide both sides by 2
y= 14/3 divided by 2
y=14/3(1/2)
y=14/6
2y=
