Use the distributive property, then solve for x.

Explanation:

The distributive states that a(b+c)=a*b+a*c. Let's use this on the parenthetical problem:

2(3x+1)=2*3x+2*1=6x+2

We now have 6x+2-9x=-1.

Next, let's combine like terms by subtracting 9x from 6x:

2-3x=-1

To get our answer, let's subtract 2 from each side...

-3x=-3

...and divide each side by -3:

x=1
