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.

Not sure what you mean, either. There is only a single value of x that satisfies each equation. I don't know how you'd turn that fact into columns.
You have to solve for x in column a, and solve for a different x in column b and compare those answers. Through algebra, you can find that Xa = -3/2 and Xb = -2 so Xb < Xa
yeah -- I think we got it!
A; 2(x-3) = 6x.
2x - 6 = 6x,
2x - 6x = 6,
-4x = 6,
X = 6/-4 = -6/4 = -3/2.
B: 3x + 2 = 5x + 6.
3x - 5x = 6 - 2,
-2x = 4,
X = -2.
Compare: A/B = (-3/2)/-2 = (-3/2) * (-1/2) = 3/4.
Therefore, A is 3/4 of B.
2x - 6 = 6x,
2x - 6x = 6,
-4x = 6,
X = 6/-4 = -6/4 = -3/2.
B: 3x + 2 = 5x + 6.
3x - 5x = 6 - 2,
-2x = 4,
X = -2.
Compare: A/B = (-3/2)/-2 = (-3/2) * (-1/2) = 3/4.
Therefore, A is 3/4 of B.
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.
Glad we could help!!
