Is the ordered pair a solution of the given system of equations?
-(2, 1), 3x + y = 7 2x + 3y = 7
A) Yes
B) No

Question

Quizplus · Accepted Answer

To check if (2,1) is a solution to the given system of equations, we substitute x=2 and y=1 in both equations and check if they are true.

3(2) + (1) = 7  --> 6 + 1 = 7 (true)
2(2) + 3(1) = 7 --> 4+3=7 (true)

Since both equations are true when x=2 and y=1 (the ordered pair given), (2,1) is a solution to the system of equations. Therefore, the answer is A.
