Are the two equations -6 + y = 2x and 2y - 4x = 12 dependent?

Yes they are linearly dependent, essentially the same equation.

Start from one of them:

-6 + y = 2x

Move things around:

y - 2x = 6

Multiply both sides by 2,

2y - 4x = 12

That's the second equation, which we've shown is equivalent to the first, so they're linearly dependent.

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
