Question

If the point (3, 4) lies on the graph of the equation 3y = ax + 7, find the value of a.​

Answer 1

$\huge\sf\red{Given:-}$

• (3,4) lies on the graph of the equation 3y=ax+7

$\huge\sf\blue{To\:Find:-}$

• value of a

$\huge\sf\green{Solution:-}$

✑According to the question,x=3 and y=4

Now, Substituting the values of x and y in the equation 3y = ax + 7,

We get,

$(3×4)$ = $(a×3) + 7$

⇒ 12 =$3a+7$

⇒ 3a = $12–7$

⇒ 3a = $5$

⇒ a = $5/3$

The value of a, if the point (3, 4) lies on the graph of the equation 3y = ax + 7 is 5/3.✓✓

Answer 2

$\huge\pink{Given:−}$

(3,4) lies on the graph of the equation 3y=ax+7

$\huge\sf\blue{To\:Find:-}$

value of a

$\huge\sf\green{Solution:-}$

✑According to the question,x=3 and y=4

Now, Substituting the values of x and y in the equation 3y = ax + 7,

We get,

$(3×4) = (a×3) + 7$

$⇒ 12 =3a+7$

$⇒ 3a = 12–7$

$⇒ 3a = 55$

$⇒ a = 5/3$

The value of a, if the point (3, 4) lies on the graph of the equation 3y = ax + 7 is 5/3.
