Solve the following system of equations algebraically for x, y, and z. Show all work.
4x - 3y + z= -10
2x + y +3z = 0
-x + 2y - 5z = 17

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)

step-by-step explanation:

teleportation

step-by-step explanation:

3xy cannot be combined with the others

2x, -5x and x are like terms
