Question 226595: How would I determine whether the ordered pair is a solution of the system of linear equations?
(3,6) 4x + y = -18
3x + 4y = 33 Answer by drj(1380) (Show Source): You can put this solution on YOUR website! How would I determine whether the ordered pair is a solution of the system of linear equations?
(3,6) 4x + y = -18
3x + 4y = 33
Solve: We'll use substitution. After moving 1*y to the right, we get: , or . Substitute that
into another equation: and simplify: So, we know that y=14.3076923076923. Since , x=-8.07692307692307.
Answer: .
