Question

if you are three years older than your cousin and both your ages sum to 25 how old are you and how old is your cousin​

Answer 1

Answer:

You are 14 years old.  Your cousin is 11 years old.

Step-by-step explanation:

Let x = cousin

Let x + 3 = you

x + x + 3 = 25

Solve out left side

2x + 3 = 25

Subtract both sides by 3

2x = 22

Divide both sides by 2

x = 11

11 + 3 = 14

Answer 2

Answer:

my age=14 years

my cousin's age=11 years

Step-by-step explanation:

x+3=my age

x     =cousin's age

x+x+3=25

2x+3  =25

      2x=25-3

      2x=22

        x=11

therefore cousin's age=11 years

my age =x+3

            =11+3

            =14 years
