Answer:

The Answer is: 1/5

Step-by-step explanation:

Let n = the number

Six times the number plus two times three is equal to three times the number plus 9:

3(6n + 2) = 3n + 9

Solve for n:

18n + 6 = 3n + 9

18n - 3n = 9 - 6

15n = 3

n = 3/15 = 1/5, The Number is 1/5

Proof:

3(6n + 2) = 3n + 9

3(6(1/5) + 6) = 3(1/5) + 9

3(6/5 + 6) = 3/5 + 9

18/5 + 18 = 9 3/5

98/5 = 9 3/5

9 3/5 = 9 3/5

Hope this helps! Have an Awesome Day!! :-)
