Question 802227
Let raquel age be x
Let bev age be y 

raquel is now 3 years older than bev
x  = y + 3 
Rewriting the above equation
x  - y = 3 -----------------------eq. 1 


 In 5 years the sum of their ages will be 79
 In 5 years
	raquel's age will be x + 5
                bev's age will be     y + 5


the sum of their ages will be 79
x + 5 + y + 5 = 79
x + y + 10 = 79
x + y = 69 ----------------------------eq.2


Solving the 2 equations(Add the 2 equations)
x  - y = 3
x + y = 69 


2x = 72
x = 72/2 = 36


Raquel's age is 36 
Bev's age is 33
