determine if the given ordered triple is a solution of the system (-3, -5, 3)
x+4y+4z = -29
3y+3z = -24
z = -3
3y + 3z = -24
3y + 3(-3) = -24
3y -9 = -24
3y = -15
y=-5
x + 4y + 4z = -29
x + 4(-5) + 4(-3) = -29
x - 20 - 12 = -29
x - 32 = -29
x = 3
so I get x=3 y=-5 z=-3
Then the given ordered triple (-3, -5, 3) IS a solution of the system?
Thanks
