Question

1.Tony and Belinda have a combined age of 56. Belinda is 8 more than twice Tony’s age. How old is each?

Answer 1

x = tony's age
y= belinda's age

Tony and Belinda have a combined age of 56.
-> The sum of their ages is 56
-> x+y = 56

Belinda is 8 more than twice Tony’s age.
-> y = 8 + 2 * x
-> y = 8 + 2x

Now you have 2 equations, solve for x and y using addition substitution or elimination!
