Answer:

35

Step-by-step explanation:

You have to work backwards, you find what 25-18 is (7)

7 is a fifth of the number you are looking for

so all you have to do is 7 x 5 and you get 35

Answer:

35

Step-by-step explanation:

We have the following equation that represents the problem:

[tex]25 - \frac{1}{5}x = 18[/tex], where x is the answer we are looking for.

We can subtract both sides by 18:

[tex]25 - 18 - \frac{1}{5}x = 0[/tex]

[tex]7 - \frac{1}{5}x = 0[/tex]

add [tex]\frac{1}{5}x[/tex] to both sides:

[tex]7 = \frac{1}{5}x[/tex]

multiply both sides by 5:

[tex]35 = x[/tex].

Here, x = 35
