Question

Six times a number decreased by ten is eight.Find the number

Answer 1

Answer:

6x - 10 = 8

6x = 18

x = 3

Step-by-step explanation:

6 times a number is 6x because we dont know the number so we assign x to the unknown then multiply by 6. Decreased by 10 simply means subtract 10. "is eight" tells you what the previous is equal to. Now, you add 10 to the - 10 to isolate x on one side of the equation. you are left with 6x = 18 because we added 10 to 8. then you want to get x alone so you divide 6x by 6, and 18 by 6. you get x=3, your answer.

Answer 2

Answer: The number is 3

Step-by-step explanation:

Let the unknown number be a

6 times a = 6a

6a - 10 = 8

We then add 10 to both sides of the equation

6a - 10 + 10 = 8 + 10

6a = 18

Divide both sides of the equation by the coefficient of a that is, 6 we have

6a/6 = 18/6

a = 3

Therefore, the number is 3
