the sum of carol's current age and her age last year 27 how old is carol?

Question

it about the age and it include addition and doubling up of the sum 

 

Answer 1

Hi Mehak, let x be Carol's current age. Then, Carol's age last year is x - 1.

 

Use the equation:  x + (x - 1) = 27, to find the value of x or Carol's current age.

 

Remove the parenthesis gives:

 

x + x - 1 = 27

 

2x - 1 = 27

 

Add 1 to both sizes of the equation gives:

 

2x = 28

 

Divide both sides by 2 gives:

 

x = 14, or Carol's current age.
