Hope this helps. Have a good day.

Answer 2

Answer:

let the number be x

therefore, 20% of x wil be= 20x

when added to 20,

20+20x,

then the number itself.

so the equation will be...

20+20x=x

If 20% of a number"   .20x

"is added to 20"  .20x + 20

"the result is the number itself."

.20x + 20 = x

Subtract .20x

20 = x - .20

20= .25x = x/4

Multiply both sides by 4
