Question

Describe and correct the error in determining wheather (8,11) is a solution of y-x=3

Answer 1

(8, 11) is the correct solution. x = 8, y = 11

Plug it in:

11-8=3

That's correct.

Answer 2

(8,11) is a solution because if you subsitute y for 11 and x for 8 then you'll 11-8 which does equal 3 so (8,11) is a solution of 3.

y-x=3

11-8=3
