Answer 2

$\large{explanation}$

given equation

2x+ay=8

ax+8y=a

for infinitely many solutions

$\frac{a1}{a2} = \frac{b1}{b2} = \frac{c1}{c2}$

comparing this we get

$\frac{2}{a} = \frac{a}{8} = \frac{8}{a}$

$\frac{2}{a} = \frac{a}{8} ..... \frac{a}{8} = \frac{8}{a}$

$a {}^{2} = 16.....a {}^{2} = 64$

$a = \sqrt{16} ......a = \sqrt{64}$

$a = 4.....a = 8$
