To find -

• The number.

Step-by-step explanation -

Let the number be "x".

Adding 10 to four times the certain number -

• We get 4x + 10.

Also -

• 5 less than five times the number is 5x - 5.

According to the Question -

• 4x + 10 = 5x - 5.

Therefore -

$\longrightarrow \: \bf4x + 10 = 5x - 5$

$\bf\longrightarrow \: 4x - 5x = - 5 - 10$

$\bf \longrightarrow \: - x = - 15$

$\bf\longrightarrow \: x = 15$

Hence -

• The number is 15.
