y = z+1 and x = -3z+6, so
(-3z+6)+2(z+1) + z = 14
so, find z, then x and y
Solve by Substitution
x + 2y + z = 14
y = z + 1
x = -3z + 6

How do I find z (or any other variable for that matter)?
−2z + 6 + 2(z+1) = 14
−2z + 6 + 2z + 2 = 14
8 = 14
I try to solve the equation but end up with this, which is false.
−2z + 6 + 2(z+1) = 14
