Question

Is (2,3) a solution to the system of inequalities 4x+3y<20 10x+y>10

Answer 1

Yes it is a solution because if you take the equation and plug the point in for the x and y :

4 (2) + 3 (3) < 20 
 8 + 9 < 20 
17 < 20
which is true

10 (2) + (3) > 10
20 + 3> 10
23>10
which is also true

Answer 2

Hope this helps..... :)
