You can put this solution on YOUR website!
y = x + 11
z = x - 18
x + 2y + 3z = 100
---
put the system of linear equations into standard form
---
y = x + 11
z = x - 18
x + 2y + 3z = 100
---
x - y = -11
x - z = 18
x + 2y + 3z = 100
---
copy and paste the above standard form linear equations in to this solver:
