Answer:
The value of "a" in the given system of equations is 16
Therefore a=16
Therefore substitute a=16 then equation (2) becomes
12x-8y=2(16)
12x-8y=32
Explanation:
Given system of equations are

and
have infinite number of solutions
To find the value of a in the given system of equations :
From given the equations have infinite number of solutions and so they refers the same line
Therefore the equation (2) becomes

( by
)





Rewritting the above equation we get

The value of "a" in the given system of equations is 16
Therefore a=16
Therefore equation (2) becomes
12x-8y=2(16)
12x-8y=32
