Halp!
what is the value of x in the equation 13 x-2(8 + 5 x) = 12-11 x?

x=2

Step-by-step explanation:

You have to distribute the -2 to the numbers inside the parentheses. So, you have to multiply 8 by -2, and 5x by -2. This gets you -16 and -10x.

Your equation would then look like this:

13x-16-10x=12-11x

From here, you can work your way through, and while there are different ways to do it, did the inverse opertions for 16, and added 16 to the 16 on the left side, and added the 16 to the 12 on the right side. (the 16 plus the -16 cancels it out on the left side)

Now your equation would look like this:

13x-10x=28-11x

13x-10x would be 3x, and then you would have an equation that would look like this:

3x=28-11x

I proceeded to add 11x to the 3x and got 14x, your equation would now be simplified to just:

14x=28

To isolate x, we divide by 14 on both sides, and 28 divided by 14 is 2. Answer would be:

x=2

correct answer:

i^31 = -i
