Question

Which of the following equations has no solution?


#1: 3x + 1 = 2x + 1
#2: 3x + 1 = 3x + 1
#3: 3x + 1 = 3x + 2

Answer 1

option 3

Answer 2

3x + 1 = 3x + 2
-3x -3x
\[1\]

Answer 3

\[1\neq2\]

Answer 4

Whenever you solve an equation which ends up in an untrue statement, the equation has no solution.

For example, x + 1 = x + 2

If you solve that equation by subtracting x from both sides, you get 1 = 2 which is an untrue statement. Therefore the equation x + 1 = x + 2 has no solutions.

Now use this concept and try to answer your question.
