Question

solve equation x/2-9=11​

Answer 1

Answer:

The answer is typed below

x/2 - 9 = 11

x/2 = 11 + 9

x/2 = 20

x = 20 X 2

x = 40

Step-by-step explanation:

Have a nice day my friend :)

Answer 2

Answer :-

$Q) \: \sf\dfrac{x}{2} - 9 = 11$

Transposing 9 from LHS to RHS, changing it's sign,

$\leadsto \sf\dfrac{x}{2} = 11 + 9$

Adding 9 to 11,

$\leadsto\sf\dfrac{x}{2} = 20$

Transposing 2 from LHS to RHS, changing it's sign,

$\leadsto\sf x = 20 \times 2$

Multiplying 20 with 2,

$\leadsto\sf x = 40$

----------------------------------

V E R I F I C A T I O N :-

• To check our answer, let's put 40 in the place of x and see whether LHS = RHS.

LHS

$\hookrightarrow\rm \dfrac{x}{2} - 9$

Substituting the value of x,

$\hookrightarrow\rm \dfrac{40}{2} - 9$

Applying the BODMAS rule and dividing 40 by 2 first,

$\hookrightarrow\rm 20 - 9$

Subtracting 9 from 20,

$\hookrightarrow\rm 11$

RHS

$\hookrightarrow\rm 11$

----------------------------------

Since LHS = RHS,

Hence verified!
