Answer 1

Step-by-step explanation:

7x - 9 = 16

» 7x = 16+9

» 7x = 25

» x = 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

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

=> $7x=25$

Divide both sides by $7$, we get

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

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