Question

2x+20%of x =12.1.
solve it .​

Answer 1

Answer:

$\huge\mathcal\pink{Answer:}$

2x + 20% of x = 12.1

⇒ 2x + (x × (20))/100 = 12.1 ⇒ 2x + 20x/100 = 12.1

⇒ 2x + 22x/10 = 12.1

(20x + 2x = 121)/10 ⇒ 22x = 121 ⇒ x = 121/22 = 11/2

∴ x = 11/2 or 5.1/2

Answer 2

Answer:

2x + 20% of x = 12.1

⇒ 2x + (x × (20))/100 = 12.1 ⇒ 2x + 20x/100 = 12.1

⇒ 2x + 22x/10 = 12.1

(20x + 2x = 121)/10 ⇒ 22x = 121 ⇒ x = 121/22 = 11/2

∴ x = 11/2 or 5.1/2
