Answer:
n=5
Step-by-step explanation:
Write an equation
The difference of 3 times a number and six
Difference means subtract. Times means multiply. And means add.
So, 3 times a number, n minus 6
3n-6
Is nine
Is means equal
= 9
3n-6=9
Solve
3n-6=9
Add 6 to both sides
3n-6+6=9+6
3n=15
Divide both sides by 3
3n/3=15/3
n=5
