Question 230823
if a * b * c = 0, then either a can be equal to 0 or b can be equal to 0 or c can be equal to 0 and the equation will be true because you will get 0 = 0.


take each factor in turn and set it equal to 0 and solve for the unknown variable.


2x-3 = 0
add 3 to both sides to get:
2x = 3
divide both sides by 2 to get
x = 3/2


that's solution D. 


x-11 = 0
add 11 to both sides.
x = 11


that's solution B.


x/3 + 7 = 0
subtract 7 from both sides to get:
x/3 = -7
multiply both sides by 3 to get:
x = 21


that's solution A.


Look's like the solution that is not a solution to your problem is C.
