-4t + 1 = 3t + 1 - 7t
Combining like terms
-4t + 1 = 1 - 4t
Adding 4t to both sides we get
1 = 1
This is called an identity. If, when solving an equation you get an identity, this means any real number can be substituted for t and you will get a true answer.
If when solving an equation you get something that is false, 2=3 for example, this means no number will solve the equation. This is called a contradicition, and we denote it's solution as `O/` (the null set).
Since the answer to this problem is an identity, it means the solution is `RR` , the real numbers.
we will just move the like terms on one side and the constants on the other,
oh,now i understand the problem why u cant get the ans.i think the question has a mistake.
hope that helped.
