Question

solve the following (i) 7x-9=16​

Answer 1

$\huge\mathfrak\pink{Solution:-}$

$7x \: - 9 \: = 16$

$7x \: = 16 + 9$

$7x \: = 25$

$x \: = \frac{25}{7} = 3 \frac{4}{7}$

Answer 2

Answer:

=> The value of x is $\frac{25}{7}.$

Step-by-step explanation:

Given that:-

$7x-9=16$

To find:- The value of the expression:

Here we will use the transposition method.

We have to follow these steps:-

( i ) First of all, we have to identify the variables and the constants.

( ii ) Get the variable to one side of the equation. Maintain equation balance while calculating.

( iii ) Then solve the expression of both sides by using various mathematical operations. Simplify both sides.

As we have,

=> $7x-9=16$

Add both sides by $9$, we get

=> $7x-9+9=16+9$

Simplifying it further, we get

=> $7x=25$

Divide both sides by $7$, we get

=> $x = \frac{25}{7}$

Hence, the required solution is $\frac{25}{7}.$
