Answer: Anothony delivers 48 milk boxes a week.
Step-by-step explanation:
12 x 4 = 48
-x + 2y = 6
6y = x + 18
Let's rewrite these equations.
-x + 2y = 6
6y - x = 18
If we multiply the second equation by -1 we can add both of them.
-x + 2y = 6
-6y + x = -18
Add:
-x + (-6y) + 2y + x = 6 + (-18)
2y - 6y + x - x = 6 - 18
-4y = -12
y = -12/-4
y = 3
Substitute y in the equation:
-x + 2y = 6
-x + 2.3 = 6
-x + 6 = 6
-x = 6 - 6
-x = 0
x = 0
