Answer:
x = 9
y = 3
Step-by-step explanation:
2x + 2y = 24 is the same as x + y = 12
using substitution, x = 12-y
12 - y = 3y
12 = 4y
y = 3
x = 3(3)
x = 9
Answer:
Yes
Step-by-step explanation:
The ordered pairs are (6,72) (8,96) (5.5, 66) (9,108) (7,84).
The number of hours worked is 
and the money earned is 
.
Let us divide the values of by
The fuction which defines the above ordered pairs is 
It can be seen that the amount of money earned is 12 times the number of hours worked.
So, per hour Jerry earns 12 dollars.
Hence, the ordered pairs are relation.
Distribute
-2(x+6)+3
-2x-12+3
-2x-12+3=-11x+4(x+4)
Distribute
4(x+4)
4x+16
-2x-12+3=-11x+4x+16
Combine Numbers && Variables
-2x-9=-7x+16
Add The 7 Over To The -2x
5x-9=16
Add 9 Over To 16
5x=25
x=5
So 5 Is Your Answer
