Liliana solved the equation below. when she tried to verify her answer, she realized she made an error.

which correction should liliana make?

B. The second step should be 1/3x + 6 - 6 = 7 - 6

Step-by-step explanation:

Liliana made the mistake of subtracting on one side and dividing on the other. When you do something to one side, you have to do the same thing to the other, hence it should be subtracting on both sides.
