Question

If x=1,y=1 is a solution of the equation 3x+ay=6,findthevalueof"a"

Answer 1

x= 1
y= 1
A/Q
3x+ay=6
3*1 + a*1= 6 ( x and y both are = 1)
3 + a = 6
so..a= 3
..so answer will be 3

Answer 2

Here is the answer

According to the question,

Given :
x = 1
y = 1

Equation : 3x + ay = 6

To find :
Value of a

Therefore,

Putting value of x and y in the given equation,

$\bf{3 × 1 + a × 1 = 6} \\ \bf{3 + a = 6} \\ \bf{a = 6 - 3} \\ \bf{a = 3}$

Hence
The Value of a is 3.
