You can put this solution on YOUR website! x = frank age
y = kayla age
z = maria age
u = george age
---
x = y - 6
z = 18
u = z - 3
u = y + 2
---
put the system of linear equations into standard form
---
x - y = -6
z = 18
z - u = 3
y -u = -2
---
copy and paste the above standard form linear equations in to this solver:
