Question

The value of x in equation 4x+3 =19is _____
​

Answer 1

4x+3=19

or it can also be written as,

4x = 19-3

or,

4x = 16

or,

x = 16/4

or,

x = 4

Therefore x = 4

Lets check :

putting x = 4

4 × 4 + 3 = 19

hence its checked

Answer 2

Answer :-

• The value of x in the equation 4x + 3 = 19 is 4.

Step-by-step explanation :-

$\sf Q) \: 4x + 3 = 19$

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

$\sf\Rightarrow4x = 19 - 3$

• On simplifying,

$\sf\Rightarrow4x = 16$

• Transposing 4 from LHS to RHS, changing it's sign,

$\sf\Rightarrow x = \dfrac{16}{4}$

• Dividing 16 by 4,

$\sf\Rightarrow x = 4.$

• The value of x = 4.

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

Verification :-

To check our answer, let's put 4 in place of x and see whether LHS = RHS.

LHS

$\tt\implies4 \times 4 + 3$

Applying the BODMAS rule and multiplying 4 by 4 first,

$\tt\implies16 + 3$

Adding 3 to 16,

$\tt\implies19.$

RHS

$\tt\implies19.$

Since LHS = RHS,

Hence verified!
