Question

The solution of equation x-2=7 is​

Answer 1

Answer:

⇢ ${\boxed{\bold{x = 9}}}$

Step-by-step explanation:

⇢ x - 2 = 7

ㅤ

To find the answer for this equation, add '2' non both sides of the equation.

⇢ $\sf{x - 2 + 2 = 7 + 2}$

⇢ $\sf{x - 2 = 2 - 2 = 0}$

⇢ $\sf{7 + 2 = 9}$

⇢ ${\boxed{\bold{x = 9}}}$

ㅤ

Therefore, this is the required answer.

Answer 2

Answer:

=> x = 9

Step-by-step explanation:

Given that:-

$x-2=7$

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,

=> $x-2=7$

Add both  sides by $2$, we get

=> $x-2+2=7+2$

=> $x=9$

Hence, the required solution is 9.
