Jenny is solving the equation 3 x + 5 = 4 x + 2 using algebra tiles. She cannot decide if she should add 3 negative x-tiles or a

dd 2 negative unit tiles to both sides first. Which explains which Jenny should do first?
A.She should add 3 negative x-tiles first because that is the only way to isolate the variable.

B.She should add 2 negative unit tiles first because that is the only way to get to the correct solution.

C.She can do either one first because zero pairs will be created to isolate the variable either way.

D.She should do neither one first because the first step is to add 4 negative tiles to both sides.
