I need help with sme math problems and i'm hoping to get some help on this website. I will post a couple more problems I need help with in the future.

Lines y=(3a+2)x-2 and 2y=(a-4)x+2 are parallel. What is the value of a ?

Let's put BOTH equations in to y = mx+b form first

y=(3a+2)X-2 AND y= (a-4)/2 x + 2/2 if they are parallel, the slopes will be equal , so

(3a+2) = (a-4)/2 then just solve for'a'

3a +2 = a/2 - 2

5a/2 = -4

5a = -8

a = -8/5
