Question

What does it mean if (2, 20) is a solution of y = 10x and x +y = 22 ?

2, 20) makes exactly one of the equations true.


(2, 20) makes at least one of the equations true.


(2, 20) makes neither equation true.


(2, 20) makes both equations true.

Answer 1

(2, 20) makes both equations true

Explanation:

If a point is a solution for 2 equations, that means that it makes both equations true.

So, since (2, 20) is a solution to both y = 10x and x + y = 22, that means it makes both of the equations true.
