Question

need help with identity problems if someone can help
3(t+2)+t=2(3+2t)<--problem start
3t+6+t=6+4t<--my work onwards
4t+6=4t+6
4t+6-6=4t+6-6
4t/4=4t/4
t=t
this problem is an identity

this is the problem and my solution but its wrong i was asked "if this is an identity what is the solution" but i dont understand what my instructor is after here

Answer 1

You have proven that it is an identity (t=t). There are an infinite number of solutions.

Answer 2

Hi, your instructor wanted you to use the Distributive Law:
a(b + c) = ab + ac

And you it looks like you did a fine job without even knowing it xD

Your solution is not wrong. T = T has infinite solutions.

Answer 3

thats pritty much what i thought but she is asking for something a solution whcih when i look at it i can see to many only thing i can guess at is she wants a number puged into the problem and then redone but not sure if there is something else shes looking for or not

Answer 4

Any number you plug in will make the problem true.

Answer 5

ill try resubmitting with a number pluged in then thanks all
