Question

Thomas and Sydney have a combined age of 57. Thomas is 13 years older than triple Sydney’s age. How old is Thomas? You must create a system of equations and use substitution to solve.

Answer 1

57-13=44. If Sydney is 11, then Thomas is 46. 11x3=33, and 33+13=46. To check our answer, we will add 46+11. 46+11=57.
