I do not understand how to figure this out ...

2 (3x+6) = 42

5

Step-by-step explanation:

2 (3x + 6) = 42

(3x + 6) = 42/2

(3x + 6) = 21

3x + 6 = 21

3x = 21 - 6

3x = 15

x = 1/3

x = 5

The answer would be x=5

Step-by-step explanation:

2 (3x+6) = 42

so what you're gonna do is use the distributive property, so you would multiply 2 and 3x, and 2 and 6. so then you would have:

6x+12=42

Now you want to get rid of the twelve so you can solve for x. So you are going to subtract 12 from 12 and 42. So now you have:

6x=30

Next you're going to divide 6x and 30 by 6. So you would have x=5
