Question 3954
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.
