Question

If X=1,Y=1 is a solution of the equation 3X+aY=6,find the value of "a"​

Answer 1

a =3

Step-by-step explanation:

3(1)+a(1)=6

a=6-3

a=3

Answer 2

$\bf \red{given}$

• value of x=1
• value of y=1

$\bf{now}$

$3x + ay = 6$

$putting \: the \: value \: of \: x \: and \: y$

$3 \times 1 + a \times 1 = 6$

$3 + a = 6$

$a = 6 - 3$

$a = 3$
