How many values of x make each statement true? Explain your reasoning.

a) 3x+3=3(x+1)

b) x-4-x=0

I don't get what the question is telling me to do.

Help?

for the first one:

3x+3=3(x+1) expand it to get

3x+3 = 3x+3

0=0

this is a true statement, so any value of x makes the original statement true.

This is an example of an "identity"

for the second:

x-4-x=0 , so

-4 = 0

this is a False statement, so NO value of x will make the original statemtent true
