The worst thing in the world is Algebra, I suck at any and all math and I am terrified of the next couple of months with it for my college courses. I have asked my Professor, but she is taking a long time to answer, so hoping for some clarity.
Linear Equations
Solve: 1/2x - 1/6x = 5
6(1/2x -1/6x) = 5 * 6
3x - x = 3
2x = 30
x=15.
ok so I get the process of multiplying in the parenthesis (PEMDAS)etc., but what I do NOT understand is WHERE they get the 6 all of a sudden. Where did they figure to multiply everything with the 6? I am SO confused on that. is it a Greatest Common Multiple or something?
Oh btw this was a sample equation during the online lecture, not something I figured out for myself
