Question 930207: Emily is 28 years younger than Stephanie. Stephanie and Emily first met two years ago. Eighteen years ago, Stephanie was 5 times as old as Emily. How old is emily?
You can put this solution on YOUR website! x = emily age
y = stephanie age
---
x = y - 28
y - 18 = 5(x - 18)
---
put the system of linear equations into standard form
---
x - y = -28
y - 18 = 5x - 18*5
---
x - y = -28
5x - y = -18 + 18*5
---
x - y = -28
5x - y = 72
---
copy and paste the above standard form linear equations in to this solver:
