Question 3954: Explain the difference between equivalent expressions and equivalent equations.
Show an example of each
Answer by longjonsilver(2297)   (Show Source):
You can put this solution on YOUR website! equivalent expressions have the same value but are presented in a different format using the properties of numbers eg, ax + bx = (a + b)x are equivalent expressions. Strictly, they are not "equal", hence we should use 3 parallel lines in the "equal" rather than 2 as shown here.
equivalent equations are equations that have the same solution eg 2x = 10 and 3x-1 = 14. Both have x=5.
