Answer:
94
Step-by-step explanation:yes it does because as you can see in the text above
X+y+z = 132
x = 7+z
y = 3z
(7+z)+3z+z = 132
5z = 132-7
z = 125/5
z = 25 <=====
x = 7+z
x = 7 + 25
x = 39 <=====
y = 3z
y = 3 × 25
y = 75 <=====
hope it helps :)
(-3, 1)
4x-9y=-21
+-4x-3y=9
-12y= -12
y=1
4x- 9(1)= -21
4x-9=-21
+9 +9
4x= -12
x=-3
