ITS SIMPLE
GIVEN THAT IN EQ. 3x + ay = 8. PASSES THROUGH THE POINT (2,2) THAT MEANS THAT (2,2) IS A SOLUTION OF THE EQUATION
THERE FOR PUTTING VALUE X= 2 AND Y = 2 IN THE EQUATION WE HAVE
3(2) + a (2) = 8
6 + 2a = 8
2a = 8-6
2a = 2
a = 2/2 = 1
Therefore value of
a = 1

Answer is 1
3x+ay=8
3*2+ay=8
6+ay=8
ay=8-6
ay=2
y=2
a*2 =2
a= 1

3Ã—2+aÃ—2=8
6+2a=8
2a=8-6
a=2/2=1ans

3x+ay=8
Since it passes through point (2,2),
Hence, (3*2)+(a*2)=8
Or, 6+2a=8
Or, 2a=8-6
Or, 2a=2
Or, a=2/2
Or, a=1
