The answer is 9 just do the absolute value of the number -9
Step-by-step explanation:
First, convert 15 2/5 to an improper fraction. (77/5)
Next, divide 77 by 11 = 7 and divide 11 by 11. Now, your ration should look like this: 7/5:1.
Last convert the improper fraction to 1 2/5:1. This is your answer.
First row
∴ x = -9
∴ (1/3)x + y = 12
(1/3)(-9) + y = 12
-3 + y = 12
∴ y = 15
Second row
∴ x = -3
∴(1/3)x + y = 12
(1/3)(-3) + y = 12
-1 + y = 12
∴ y = 13
Third row
∴ x = 0
∴(1/3)x + y = 12
(1/3)(0) + y = 12
0 + y = 12
∴ y = 12
Fourth row
∴ x = 3
∴(1/3)x + y = 12
(1/3)(3) + y = 12
1 + y = 12
∴ y = 11
Fifth row
∴ x = 9
∴(1/3)x + y = 12
(1/3)(9) + y = 12
3 + y = 12
∴ y = 9
