Question 326888
To solve this problem, you are going to have to first write two equations using what you know.
First, you know that Tony and Belinda have a combined age of 56.  This can be written as:
T + B = 56 (where T = Tony's age, B = Belinda's age)
Second, you know that Belinda is 8 more than twice Tony's age. This can be written as:
B = 8 + 2T
Now you can plug in the second equation into the first equation for B and solve for T:
T + B = 56
T + (8 + 2T) = 56
8 + 3T = 56
3T = 48
T = 16
So Tony is 16 years old.
Now plug this into the first equation to find B:
T + B = 56
16 + B = 56
B = 40
So Belinda is 40 years old. 

Hope that helps!
