x = age younger car
y = age older car
---
x + y = 11
y + 5 = 2(x + 5) + 3
---
x + y = 11
y + 5 = 2x + 10 + 3
---
put the system of linear equations into standard form
---
x + y = 11
-2x + y = 10 + 3 - 5
---
x + y = 11
-2x + y = 8
---
copy and paste the above standard form linear equations in to this solver:
