B. 3x+6=18

1) how can we get equation b from equation a?


This is due today and I really don’t get it.

Answer 1

you just multiply 3*(x+2) from the equation and that will give you 3x+6 and then you just bring down the =18 and then you have 3x+6=18

Answer 2

you are distributing

Explanation:

how this works is your distributing 3 into both things in () so in this case your are putting 3 into x which gives you 3x and 3 x 2 is 6. Hope this helps!
