Answer:

3x-1/9 y=18

if y=27

Then:

3x-(1/9)27=18

3x-27/9=18

3x-3=18

3x=18+3

3x=21

x=21/3=7

Answer: x=7

Answer:

x = 15

Step-by-step explanation:

3x - 1 y = 18

Let y=27

3x - 1*27 = 18

3x -27 =18

Add 27 to each side

3x-27+27 = 18+27

3x = 45

Divide each side by 3

3x/3 = 45/3

x = 15
