You can put this solution on YOUR website! x = your age
y = mother age
---
y = 2x + 12
y + 8 = 3(x + 8) - 20
y + 8 = 3x + 24 - 20
y + 8 = 3x + 4
---
put the system of linear equations into standard form
---
2x - y = -12
3x - y = 4
---
copy and paste the above standard form linear equations in to this solver:
