Answer :

x = 10

Step-by-step explanation :

2x - 9 = 11

⇒ 2x = 11 + 9

⇒ 2x = 20

⇒ x = $\frac{20}{2}$

⇒ x = 10

Check Your Solution :

Putting the value of x, we get ;

2x - 9 = 11

Solving LHS = 2x - 9

= 2 * 10 - 9

= 20 - 9

= 11

Hence, LHS = RHS.

Therefore, the value of x is 10.

To find :

The required value of x

Solution :

2x -9 = 11

Transfering 9 right hand side :

[ This side 9 was in subtraction , that side it will be in addition]

2x = 11+9

2x = 20

Transfering 2 right hand side :

[2 was in multiplication this side on that side it will be in division]

x = 20/2 = 10
