Answer :

Answer:

3*x + y = 25

Step-by-step explanation:

Here we have the sentence:

"three times a number (let's call it x) added to another number (let's call it y) gives 25"

We can write this as:

3*x  (3 times the first number)

+  y  (added to another number)

= 25  (gives 25)

Writing this as an equation, we get:

3*x + y = 25

This is the equation we wanted.
