Answer:
Subtract 1x from both sides
B) Add/subtract the same quantity to/from both sides
Explanation:
I glanced over both equations and noticed only one thing was really different from them bot. There was an extra x in equation A. Then I noticed if you add the 1x t both sides of equation A than it would be the same as equation B. That is when I realized that equation B needed 1x subtracted from both sides.
A) Add/subtract a quantity to/from only one side
B) Add/subtract the same quantity to/from both sides
C) Multiply/divide only one side by a non-zero constant
D) Multiply/divide both sides by the same non-zero constant
