Answer:
x = 5
y = 3
Step-by-step explanation:
substitute x-2 for y in the other problem
X = 17-4(x-2) do your substituting and get x = 5
now you have x plug it into y = x-2
y = 5-2
y = 3

Answer:
-2x+2y+3z=0
-2x-y+z=-3
2x+3y+3z=5
---------------
-2x+2y+3z=0
-2x-y+z=-3
---------------- Subtract
3y + 2z = 3 Eqn A
=========================
-2x-y+z=-3
2x+3y+3z=5
---------------- Add
2y + 4z = 2
6y + 4z = 6 Eqn A times 2
------------------------------------ Subtract
-4y = -4
y = 1
-----------------
z = 0
-------------------
x = 1
Answer:
1/24 ≈ 4.2%
Step-by-step explanation:
P(head) = 1/2
P(4) = 1/6
P(2 heads and 4) = (1/2)² (1/6) = 1/24 ≈ 4.2%.
