Question

Is (2, 2) a solution of the system y = x and x + 2y = 6?

Answer 1

Answer:

Yes.

Step-by-step explanation:

2=2, yes

2+2(2)=2+4=6, yes

Answer 2

Answer:

yes

Step-by-step explanation:

Substitute x = 2 and y = 2 into both equations and if both are true then (2, 2) is a solution of the system.

y = x, that is

2 = 2 ← True

x + 2y = 6, that is

2 + 2(2) = 2 + 4 = 6 ← True

Thus (2, 2) is a solution of the system
