• Substituting the value of a in

$\bf \green{2x + ay = 5 \: \: ,we \: have}\\ \bf \red{2x - 3y = 5}$

Take x= 4

$\tt \blue{2(4) - 3y = 5 }\\ \longrightarrow \tt \pink{ - 3y = - 3 \rightarrow \: y =1 }$

Now Take x= -2

$\tt \purple{2( - 2) - 3y = 5} \\ \tt \orange{ - 4 - 3y = 5}\\ \longrightarrow \: \tt \gray{ - 3y = 9 \rightarrow \: y = - 3}$

Thus, (4,1) and (-2,-3) are two more solutions of the equation2x-3y=5.
