Answer:

Table is attached

Step-by-step explanation:

We are given equation as

3x+y=15

We will complete each column

First column:

we are given x=2 and we have to find y

3\times 2+y=15

6+y=15

y=9

Second column:

we are given y=3 and we have to find x

3x+3=15

3x=12

x=4

Third column:

we are given x=6 and we have to find y

3\times 6+y=15

18+y=12

y=-6

Fourth column:

we are given x=0 and we have to find y

3\times 0+y=15

0+y=15

y=15

Fifth column:

we are given x=3 and we have to find y

3\times 3+y=15

9+y=15

y=6

Sixth column:

we are given y=0 and we have to find x

3x+0=15

3x=15

x=5

Seventh column:

we are given y=8 and we have to find x

3x+8=15

3x=7

x=\frac{7}{3}

now, we can complete table

Robin can clean 72 rooms in 6 days how many can he clean in 9 days
Monica [59]
Let's put it this way. 
It's a ratio of 6:72 and we need to change it in a way to find number of rooms cleaned in 9 days.

Divide 6 & 72 both by 2
Ratio is now 3:36

Multiply 3 & 36 both by 3
Ratio is now 9:108

The number of rooms in which Robin can clean in 9 days is 108 rooms.
