Question

x-2=7 find the value of x​

Answer 1

Given data:

x - 2 = 7

To find:

The value of x

Step-by-step explanation:

Given, x - 2 = 7

⇒ x - 2 + 2 = 7 + 2 [ add 2 to both sides ]

⇒ x = 9 [ since, - a + a = 0 ]

Answer:

The value of x is 9.

NOTE:

We can also apply transposition to find the value of x.

Given, x - 2 = 7

⇒ x = 7 + 2 [ since 2 has negative symbol in the left hand side, it becomes positive when transposed to the right hand side ]

⇒ x = 9

Answer 2

Answer:

=> The value of 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.

As we have,

=> $x-2=7$

Now, add $2$ on both sides we get

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

Add the numbers, we get

=> $x = 9$

Hence, the required solution is 9.
