Given,
$\left\{\begin{array}{c}4x+y=3\\ 2x-3=y\end{array}$
Step 2
Put x=−1 & y=7 in 4x+y=3, we get
4(−1)+7=3
$⇒-4+7=3$
$⇒3=3$ which is true.
Now put x=−1 & y=7 in 2x−3=y, we get
2(−1)−3=7
$⇒-2-3=7$
$⇒-5=7$ which is not true.
Hence the given ordered pair is not the solution of given system of equations.
