I'm desperate. I'm not a cheat. But I need someone to do this so that I can see how it's done. I TRIED. I'm totally stuck, and the answer page doesn't show jack. Please, I'm desperate. I asked like 5 people, and everyone tells me, "just substitute the letters for the numbers". Okay, I KNOW but, hello! This is a complex question, and there's like 3 letters beside each other! OMG HELP PLEASE.
This is it: Find the value of 3y(2xz+2) - 6xyz when x = -4, y = -3, and z = 7.
Oh and I KNOW it's done like this,
= 6xyz + 6y - 6xyz
= 6y
= 6 (- 3)
= - 18
But this makes no sense to me. I mean, I stare at it and I stare at it. I went through 3 coffees staring at this question. I can't figure it out. Can someone offer any type of explanation? I'd be so grateful. I'm self-teaching. I'm taking my GED tests. Please, please.
