x=9÷3

x=3

Step-by-step explanation:

Answer 2

Answer:

=> The value of x is $-\frac{1}{3} .$

Step-by-step explanation:

Given that:-

$7 - 9x =10$

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,

=> $7 - 9x =10$

Rearranging the terms, we get

=> $- 9x +7=10$

Subtract both sides by $7$, we get

=> $- 9x +7-7=10-7$

=> $-9x = 3$

Now divide both sides by $-9$,

=> $x = -\frac{3}{9}$

Canceling the terms, we get

=> $x = -\frac{1}{3}$

Hence, the required solution is $-\frac{1}{3} .$
