How can you use expressions and models to determine if expressions are equivalent

To check for equivalence, use properties of operations such as the Distributive Property. Two expression are said to be equivalent if they resulted in the same number after evaluation of each. You can both expand and factor expressions to generate equivalent expressions. 

step-by-step explanation:

no of data

divide by no of mode

you can't solve x because it is 2 linear equation and you only have one equation
