Answer:
Mary = 34, George = 16, Carrie = 8, Jennifer = 10
Step-by-step explanation:
Set up the system of equations from the given information.
1) m = g + 18
2) g = 2 * c
3) c = j - 2
4) j = 10
Solve each equation one by one:
Plug eq.4 into eq.3:
5) c = 10 - 2 = 8
Plug eq.5 into eq.2:
6) g = 2 * 8 = 16
Plug eq.6 into eq.1:
m = 16 + 18 = 34
Answer:
The answer you get is x=-3, and y=5 or (-3,5)
Step-by-step explanation:
3x+y=-4 and 5x-2y = -25.
Firstly, to solve the equation let's use the multiplication method.
5x-2y=-25 (Multiply by 1)
3x+y=-4 (Multiply by 2)
=
5x-2y=-25
+6x+2y=-8
=
11x=-33
x=-3
We know that x=-3, now we can find y by substituting this value into other equations.
5(-3)-2y=-25
-15-2y=-25
+15 +15
-2y=-10
y=5
The answer you get is x=-3, and y=5 or (-3,5)
