and
"The ordered pair (7, 19) is not a solution to the system because it makes at least one of the equations false."
i took the test, this is the right answers. good luck!
The ordered pair [tex](x,y) = (7,19)[/tex] is not a solution to the system because it makes at least one of the equations false.
In this question we must evaluate the system of equation given and check if resulting identity is observed.
If we know that [tex](x,y) = (7, 19)[/tex], then we have the following result:
[tex]\left \{ {{2\cdot x - y =-5} \atop {x+3\cdot y=22}} \right.[/tex] (1)
First equation
[tex]2\cdot (7) -19 = -5[/tex]
[tex]-5 = -5[/tex]
Second equation
[tex]7 + 3\cdot (19) = 22[/tex]
[tex]64 = 22[/tex] (CRASH!)
The ordered pair [tex](x,y) = (7,19)[/tex] is not a solution to the system because it makes at least one of the equations false.
