Question

75% of a number when added to 75 is equal to this number the number is

Answer 1

Let x stand for the "mystery number" you are trying to find.

 

75% of x plus 75 = x

 

0.75x + 75 = x

 

Bring the variable terms to the left side of the equation by subtracting x from both sides.

-0.25x + 75 = 0

 

Bring the constant terms to the right side by subtracting 75 from both sides.

-0.25x = -75

 

Divide both sides by -0.25

 

x = 300
