3
No Solution (NS)
Note that we have variables on both sides of the equation. So we will subtract 3x from both sides to eliminate the 3x on the right side of the equation. However, something odd happens
That can't be right! We know that 5 does not equal 2.
It is a false statement to say that 5=2, so we know that there can be no solution.
4
Infinite solution (IS)
We have variables on both sides of the equation. So we will subtract 3x from both sides to eliminate 3x on the right side of the equation. However, something odd happens.
When does 2 = 2? All the time! This means that i does not matter what value we substitute for x, the equation will always be true.
Sometimes we use the infinity symbol♾️ to represent infinite solutions.
