4. Linear Equations in Two Variables
easy
જો $3y = ax +7 $ ના આલેખ પર બિંદુ $(3, 4) $ હોય, તો $a$ ની કિંમત શોધો.
A
$\frac{5}{3}$
B
$\frac{4}{3}$
C
$\frac{3}{5}$
D
$1$
Solution
The point $(3,4)$ lies on the graph of $3 y=a x+7.$
Substituting $x=3$ and $y=4$ in the given equation $3 y=a x+7,$ we get
$\therefore \quad 3 \times 4=a \times 3+7$
$\Rightarrow \quad 12=3 a+7 \Rightarrow 3 a=5 \Rightarrow a=\frac{5}{3}$
