Answer 2

Answer:

$\frac{18}{7}$

Step-by-step explanation:

Given :

To find the value of y,

if the equation $7y + 13 = 31$,.

Solution :

We can find the value of y by applying all the the functions both the sides,

Function 1 :

Subtracting 13 both the sides from the given equation ,

$(7y + 13) - 13 = (31) - 13$

$7y= 18$

Function 2 :

Dividing by 7 both the sides, to get the value of x,

$\frac{7y}{7} = \frac{18}{7}$,.

⇒ $y = \frac{18}{7}$,.

∴ The solution of the equation $7y + 13 = 31$ is $y = \frac{18}{7}$
