Answer : 5

As per the provided information in the given question, it has been stated that if 6 is subtracted from five times of a certain number, the result is 19. And, we have been asked to calculate the number.

Basically, we'll have to assume the unknown number as a variable & have to form a linear equation as per the given statements in order to find the number. Let us assume the number as x.

Now, according to the question, if 6 is subtracted from five times of a certain number, the result is 19. Writing this statement in the form of a equation, we get :

$\longrightarrow\sf{5x - 6 = 19}$

Now, we'll use transposition method in order to solve this equation. In transposition method, we transpose the terms from LHS to RHS and vice-versa and arithmetic operators also get changed during this method.

$\longrightarrow\sf{5x = 19 + 6}$

$\longrightarrow\sf{5x = 25}$

$\longrightarrow\sf{x = \cancel{\dfrac{25}{5}}}$

$\longrightarrow\boxed{\pmb{\sf{\purple{x = 5}}}}$

∴ The number is 5.
