Solve the system of equations:
x - y - z = 2
x + 2y - 2z = 3
3x - 2y - 4z = 5
I know how to do the whole process, but sometimes I make careless errors that I never catch when I go over my work. This is the answer I worked out:
x = 5
y = 1
z = 2
could somebody please let me know if I'm correct?

to check if your answers are correct just plug in the values you found into each of the equations.
Make sure they work for all 3 equations, answers might work in one equation but not in the other. In that case you would have made a mistake.
BTW, you are right!
