The pair of the equations 3x-2y=22 and 2x+9y=-37 have a perfect solution at ( 4,-5 ).
What is an equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Given that:-
- which systems of linear equations have the ordered pair(4,-5)as a solution
Checking the equations at the point (4,-5) if the equation will satisfy this point then it will be the solution
3x - 2y = 22
3 ( 4 ) - 2 ( -5 ) = 22
12 + 10 = 22
22 = 22
Now for the second equation:-
2x + 9y = -37
2 ( 4 ) + ( 9 x - 5 ) = -37
-37 = -37
Therefore the pair of the equations 3x-2y=22 and 2x+9y=-37 have a perfect solution at ( 4,-5 ).
