2/3 of the sum of three times a number and six is 10. what is the number?

mestny [16]

9514 1404 393

Answer:

Step-by-step explanation:

Let x represent the number. The problem statement tells you ...

2/3(3x +6) = 10

2x +4 = 10 . . . . . . use the distributive property

x +2 = 5 . . . . . . . . divide by 2

x = 3 . . . . . . . . . . .subtract 3

The number is 3.

<em>Comment on the solution</em>

The above shows an "alternative" solution method. The more usual way this might be done is ...

2(3x +6) = 30 . . . . . multiply by 3 to clear fractions

6x +12 = 30 . . . . . . . eliminate parentheses

6x = 18 . . . . . . . . . . . subtract 12

x = 3 . . . . . . . . . . . . divide by 6
