If  \: x=2, y=3   \: \: is \: \:   a  \: \:  solution   \: \: of   \: \: the  \: \:  equation\:  \:  4x+ay=23,  \\  find \:  \:  the  \: \: value  \: \:  of \:  \:  'a' \: .

\huge\red{\boxed{Answer}}

If \: we \: substitute  \: the  \: given  \: values  \: of  \: x \:  and \:  y  \: in \:  the \:  equation , \\

we \:  can  \: get  \: the  \: value  \: of  \: a.

4x + ay = 23 \:  \:  \:  \:  \:  \:  \:  \\ 4(2) + a(3) = 23 \\ 8 + 3a = 23 \:  \:  \:  \:  \:  \:  \:  \:  \: \\ 3a = 23 - 8\:  \:  \:  \:  \:  \:  \:  \:  \:  \\ 3a = 15 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \:  \:  \:  \:  \:  \:  \\ a =  \frac{15}{3}\:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \\ a = 5 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \:  \:  \:  \:  \:  \:  \:

\large{\boxed{∴  \: , The\:value\:of\:'a'\:is\:5.}}

Hope \:   \: this \:   \: helps  \: \:  you \: !
