Answer 1

let the number be X

according to the question

75x/100 + 75 = x

75x/100 = x-75

75x = 100(x-75)

75x = 100x-7500

75x-100x=-7500

-25x=-7500

x= -7500/-25

x = 300

Answer 2

Let the number be x


According to the question,

75% of x + 75 = x

$\dfrac{75}{100}$x + 75 = x

By transporting,

$\dfrac{75}{100}$ - x = -75

$\dfrac{-25}{100}$ = -75

x = $\dfrac{-75 * 100}{-25}$

x = 300
