Question 26377: I want to make sure I did this correctly:
Add 8a - 6 and 4a + 5
Now I can simplify this equation by doing the first equation like this:
8a - 6 = 2a
The second equation I did this:
4a + 5 = 9a
Now I can combine these to be:
2a + 9a = 11a
Is this the correct method?

Question 26376: 6x + 4(3x - 2) = 6x + 2
First I used the distributive process which broke it down to this:
6x + 12x - 8 = 6x + 2
Then I simplified the 6x and 12x which did this:
18x - 8 = 6x + 2
Then I had to get the x's on one side and the numbers on another:
18x - 6x = 12x
6x - 6x = 0
So the formula looked like this:
12x - 8 = 2
From here I became stuck with this. I did not know the next step. Could you please give me a hand? Thank you so much!
