Question

Find the value of x in 10x + 8 = 38​

Answer 1

Answer:

10x=38-8

10x=30

x=30/10

x=3

Answer 2

Answer :-

$Q) \: \sf10x + 8 = 38$

Transposing 8 from LHS to RHS, changing it's sign,

$\hookrightarrow\sf10x = 38 - 8$

Subtracting 8 from 38,

$\hookrightarrow\sf10x = 30$

Transposing 10 from LHS to RHS, changing it's sign,

$\hookrightarrow\sf x = \dfrac{30}{10}$

Dividing 30 by 10,

$\hookrightarrow\sf x = 3$

• The value of x is 3.

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

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

• To check our answer, let's put 3 in the place of x and check whether LHS = RHS.

LHS

$\Rightarrow\rm10x + 8$

Substituting the value of x,

$\Rightarrow\rm10 \times 3 + 8$

Applying the BODMAS rule and multiplying 10 with 3 first,

$\Rightarrow\rm30 + 8$

Adding 8 to 30,

$\Rightarrow\rm38.$

RHS

$\Rightarrow\rm38.$

Since LHS = RHS,

Hence verified!
