Answer 1

Question:

$7x-9=16$

To Find:

Find the value of x in the equation.

Solution:

$7x-9=16\\7x=16+9\\7x=25\\x=\frac{25}{7}$

Hence, the value of x is $\frac{25}{7}$

Answer 2

Answer:

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

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,

=> $7x-9=16$

Now, add both sides by $9$ we get-

=> $7x=25$

Divide both sides by $7$, we get

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

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