Detailed step-by-step solution:
Solving for x in 3(6x+8)=18x−12:
3(6x+8)=18x−12 (solving the bracket for the L.H.S. using the distributive property)
18x+24=18x−12 (18x is common on both the sides; hence, eliminating it)
24=−12
LHS ≠ RHS
Since 24 is not equal to −12, the original equation can never be satisfied by any value for x.
Therefore, it has no solution
So, option A is the correct answer.
