Compare the quantity in Column A with the quantity in Column B. Column A: 2(x - 3) = 6x Column B: 3x + 2 = 5x + 6 Could someone help me with the steps to figure this out? I'm having trouble solving these.

Can I get some help with this question? "If C is a 5 x 1 matrix and D is a 3 x 5 matrix, what are the dimensions of DC?"

I'm suppose to solve for x, but my textbook never covered how to solve this: | 5x - 8 1 |. | 2 1 | | 3 4m - 1| = | 3 7m+ 6| Can someone please help me ?

Ohhh I get it now. I'm homeschooled and my textbook always explains it badly so I was confused, but now I understand. Thanks y'all, I really appreciate the help.

I love how both of you guys wrote the same thing at the exact same time. lol

For some reason, my course skipped over matrix multiplication, but Ill look it up online. Thank you.
