Question

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

Answer 1

first thing i always do with this type of problem is to make a chart

Answer 2

tony = x
Belinda = 8+2x
making sense so far ?

Answer 3

yes so far it is

Answer 4

ok so now we know that combined age is 56 so what do you think we do with the two to set up an equation?

Answer 5

t + b = 56
8 + 2t = b

Answer 6

to set up an equation
x+8+2x=56

Answer 7

does that make sense ? because we have a total now combine like terms

Answer 8

oh okay so it would be 8 + 3x = 56 ??

Answer 9

yes now we want to get the x onto one side

Answer 10

x = 16 right?

Answer 11
