Answer:

x=11/2

Step-by-step explanation:

2x+20% of x=12.1

⇒ 2x +(20/100)x = 121/10

⇒ 2x + (x/5) = 121/10

⇒ 11x/5 = 121/10

⇒ x = (121/10)× (5/11)

∴ x = 11/2

Given :

2x + 20% of x=12.1

To find :

The value of x.

Solution :

=> 2x + 20/100x = 12.1

=> 2x + 20x/100 = 12.1

=> 2x + x/5 = 12.1

=> 10x+x/5 = 12.1

=> 11x = 5*12.1

=> 11x = 60.5

=> x = 60.5/11

=> 5.5

Hence, The value of x is 5.5

Check results :

2(5.5) +20% of 5.5=12.1

=> 11 + 1.1 = 12.1

=> 12.1 = 12.1

Hence, verified.
