Question

2x+7y=1
Y=4x-8
Is (4,8) a solution of the system

Answer 1

No it is not a solution

Explanation:

I did it on khan academy and got it right;)

Answer 2

(4,8) is not a solution

Explanation:

Check the point in both equations to see if it is a solution to both

2(4) +7(8) =1

8+56=1

This is not true so it cannot be a solution

We do not need to check the second equation because it is not a solution to the first
