QuesTion :-

Find a number such that when 5 is subtracted from 5 times that number, the result is 4  more than twice the number.

SoluTion :-

Let the number be x

According to the question,

$\tt{5x - 5 = 2x + 4}\\\\\\\tt {\implies 3x = 4 + 5}\\\\\\\tt {\implies 3x = 9}\\\\\\\tt {\implies x = 3}$

Verification :-

$\tt{5(3) - 5 = 2(3) + 4}\\\\\\\tt {\implies 3(3) = 4 + 5}\\\\\\\tt {\implies 3(3) = 9}\\\\\\\tt {\implies 3 = 3}$

So, the number is 3.
