Question

Find ‘a’, if linear equation 3x – ay = 6 has one solution as (4, 3). with proof photo

Answer 1

Answer:

a = 2

Step-by-step explanation:

If (4, 3) is the solution of 3x - ay = 6

then,

3×4 - a × 3 = 6

12 - 3a = 6

12 - 6 = 3a

6 = 3a

a = 6/3 = 2

Hope you got your answer

Have a great day ahead

Take care

Answer 2

Step-by-step explanation:

Have Given :-

Linear equation –

$3x - ay = 6$

$\scriptsize{ \because {The \: line \: passes \: through \: the \: point \: (4, 3)}}$

∴ Substituting the values of x = 4 and y = 3 in the equation –

$3(4) - a(3) = 6$

$12 - 3a = 6$

$- 3a = 6 - 12$

$- 3a = - 6$

$a = \frac{ \cancel- \cancel6}{\cancel - \cancel3}$

$a = 2$
