Help me here, logic is taking over:

A cannot equal C becaue if C were A then A would equal A where C was A

If A and C are Varibles but are the same number, then they would be the same variable.

Help me here, logic is taking over:

If A and C are Varibles but are the same number, then they would be the same variable.

statements like ‘if A=B and B=C then A=C’ are used to simplify larger problems by substituting A B and C for equations that are known to be equal in the first two ways mentioned so that you can infer that they are also equal in the third way mentioned.

you can have the same value and be different…

more than one way to interpret that statement

yes the varibales would be the same…that’s the point of the equation.

Example:

you are given:

3X+5=2Y and Y-7=2Z. solve for Z in terms of X

since Y=(3X+5)/2, you can substitute that into the eqation for Z, yielding:

2Z=(3X+5)/2-7

Z=1.5X-4.5

It’s just substitution,see. in the orignal situation you described, Z and C are two different names for the same variable.

O well, just having logical fun but you guys aren’t playing along
