Answer 2

Answer:

=> The value of x is 2, and

Step-by-step explanation:

Given that:-

$x+7=9$

We have to find the value of x and also check that the value of x satisfies the equation or not,

For solving the equation we use the transposition method,

=> $x+7=9$

Subtract both sides by $7$,

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

Simplifying it further,

=> $x = 2$

Now plug the value of x in the equation:

=> $x+7=9$

=> $2+7=9$

Add the numbers, we get

=> $9=9$

LHS = RHS
