Question 926051: Kevin is 15 years older than Jessica. Kevin and Jessica first met two years ago. Eighteen years ago, Kevin was 4 times as old as Jessica.
You can put this solution on YOUR website! x = kevin age now
y = jessica age now
---
x = y + 15
x - 18 = 4(y - 18)
---
x = y + 15
x - 18 = 4y - 72
---
x = y + 15
x - 4y = -54
---
put the system of linear equations into standard form
---
x - y = 15
x - 4y = -54
---
copy and paste the above standard form linear equations in to this solver:
