Noah is solving an equation and one of his moves is unacceptable. Here are the moves he made. 2(x+6)-4=8+6x Which answer best explains why the “divide each side by step” is unacceptable? A: When you divide both sides of by you get . B: When you divide both sides of by it could lead us to think that there is no solution while in fact the solution is . C: When you divide both sides of by you get . D: When you divide both sides of by x it could lead us to think that there is no solution while in fact the solution is x=3. Lin says that a solution to the equation 2x-6=7x must also be a solution to the equation 5x-6=10x. Write a convincing explanation about why this is true.
