Step-by-step explanation:
2x+20% of x=12.1

⇒ 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.
