Answer: The answer is: One solution.
Infinitely Many Solutions - The unknown x assumes infinite numerical values. Thus, the equation has infinite solutions.
Ex: x+2=x+2
No solution: It has no solution.
Example:
0x = 4 → Unable to divide 4 by 0.
Step-by-step explanation: These are equations that admit at least one solution.
3x+9+4x+x=
3x+4x+x=9
8x=9
x=<u>9</u>
