Answer:

Step-by-step explanation:

Let x be the number.
Set up an equation:
2x - 2/3x = 20
Simplify:
1 1/3x = 20
Divide both sides by 1 1/3
X = 15
The number is 15
Answer:
Step-by-step explanation:
Any digit will work if remainders are allowed.
If you want only whole number results
9132/12 = 761
9432/12 = 786
9732/12 = 881
X= 3
Cancel 3 out by subtracting it by itself, then subtract 3 from 18 to get 15. Now that you have 5x= 15, just divide 15 by 5x to get x= 3
