Help me solve this word problem

the sum of the ages of cindy and her dad are 39. three times cindy's age plus her dad's age is 53. what are the ages of cindy and her dad


the answer is cindy is 7 and her dad is 39 but i need to know how that is the answer

C= cindy's age
D= her dad's age
C+ D = 39
3C + D = 53

2C=14
C= 7

7 + D = 39
D = 32

If you attempt to verify the answer with the information given you will see that something is wrong somewhere.
This tells you that you need to be more careful!

I will assume you meant that dad is 32.

Cindy's age = x
Dad's age = y

x + y = 39
3x + y = 53

sub first from second -->

2x = 14
x = 7

Substitute
7 + y = 39
y = 32

Check in other equation.

The answer provided by your teacher is wrong.
x + y = 39
3x + y = 53
You will get the answer x = 7 and y = 32.
