How many values of x make each statement true? Explain your reasoning.
a) 3x+3=3(x+1)
b) x4x=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:
x4x=0 , so
4 = 0
this is a False statement, so NO value of x will make the original statemtent true 
Thank you sooo much.
