Which is the correct algebraic expression for "6 less than 3 times a number?

Step-by-step explanation: We can break this problem down to understand it.  Let the number be m. Three times the number 'm ' is 3.m or 3m. 3 ( m ) - 6 = 15. 3m -6 = 15 add 6 to both sides; 3m -6 + 6 = 15 + 6 3m = 21 dividing both the sides by 3 ,and  we get; 3m /3 = 21 / 3 m=7 .

Best of Luck!
