Answer:
There will be No solution for the equation
. Option B is correct.
Step-by-step explanation:
We need to determine how many solutions the equation
have.
Solving the equation and finding the solutions

Combining like terms, Moving 3x and 12x to left side of equality and changing their signs and moving 4 on right side of equation and changing sign.

Simplifying

Solving the equation we get 0=9 which is false. So, there will be No solution for the equation
. Option B is correct.
