Question

Is (1, 2) a solution of the system y>2x and x+y<3?

Answer 1

It is not a solution. 2x=2 and 2 is not bigger than 2 (which is y).

x+y = 1+2=3. # is not bigger than 3.

Answer 2

no

Explanation:

Let's check the first statement. 1 > 2 * 2 becomes 1 > 4. This is a false statement so the answer is no.
