Question 1177584


Jami, Ryan, and Sandra decided to create a riddle to reveal their ages.  Jami is 5 years older than Ryan.  Ryan is 7 years older than Sandra.  The sum of their ages is 73.   Write equations for this situation and use the equations to determine each person’s age.

let sandra be x years
Ryan age = x+7
Jami,s age =x+12

x+x+7+x+12=73
3x+19=73
3x = 54
x= 18  Sandra's age
