Complete table is

x: 2, 4 , 6, 0, 3, 5, 2.33

y: 9, 3 , -3, 15, 6, 0, 8

Here's a more detailed explanation of how I filled in the missing values:

x = 2:

We plug 2 into the equation for x and solve for y:

y = 15 - 3x

= 15 - 3(2)

= 15 - 6

= 9

x = 6:

Similarly, when x is 6:

y = 15 - 3x = 15 - 3(6)

= 15 - 18 = -3

x = 0:

This one's straightforward:

y = 15 - 3x = 15 - 3(0)

= 15 - 0

= 15

x = 3:

Now we need to solve for x when y is known:

y = 15 - 3x = 15 - 3(3)

y = 15 -9

y = 6

y = 0

Same process:

x = (15 - 0) / 3

x = (15 ) / 3

x = 5

y = 8:

Same process:

x = (15 - y) / 3

= (15 - 8) / 3

= 7 / 3

= 2.33 (rounded to 2 digits)

Question:-

complete table with values for x or y that make this equation true: 3x+y=15

x 2 __ 6 0 3 _ __

y __ 3 __ __ _ 0 8
