Answer :
ANSWER:
The ordered pair is NOT a solution.
STEP-BY-STEP EXPLANATION:
We have the following equation:
[tex]2x+3y=7[/tex]The ordered pair (2, -1) is a solution of the equation if, substituting the values, the equation is true, just like this:
[tex]\begin{gathered} 2\cdot2+3\cdot-1=7 \\ 4-3=7 \\ 1\ne7\rightarrow\text{ false} \end{gathered}[/tex]Which means that it is not a solution of the equation
