Answer 2

Answer :-

• x = 12.

Step-by-step explanation :-

$\sf Q) \: 27 = 2x + 3$

Transposing 3 from RHS to LHS, changing it's sign,

$\sf\Rightarrow27 - 3 = 2x$

On simplifying,

$\sf\Rightarrow24 = 2x$

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

$\Rightarrow \sf\dfrac{24}{2} = x$

Dividing 24 by 2,

$\sf\Rightarrow12 = x.$

• Therefore, the value of x = 12.

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

Verification :-

To check our answer, let's put 12 in the place of x and see whether LHS = RHS.

LHS

$\sf\Rightarrow27.$

RHS

$\sf\Rightarrow2 \times 12 + 3$

Multiplying 2 by 12,

$\Rightarrow\sf24 + 3$

Adding 3 to 24,

$\sf\Rightarrow27.$

Since LHS = RHS,

Hence verified!
