Answer:
x = 1, y = 4
Step-by-step explanation:
This is very simple
Since you have 2 equations with the same coefficient of x, just minus one equation from another:
x + 3y = 13
-
x + 2y = 9
1y = 4
Sub y = 4 into any of the 2 equation,
x + 3(4) = 13
x + 12 = 13
x = 13 - 12
= 1

Answer:
5.00
Step-by-step explanation:
the price for 3 avacados is 3.00 because 6 are 10 if you divide 10 by 2 you get 5
You add 4 on both sides so the 4 cancels out and you know have 23+4= 27
D=27
