Answer:
D
Step-by-step explanation:
for A if you subtract 3 from both sides and divide by 10 from both you get x = 0 so that has infinate solutions
for B you add 8 to both sides and divide by 16 getting the same thiong as A
For C you ditribut 4 to 2x and -3 getting 8x-12=8x-12 if you solve it you get the answer as A & B
For D if you subtract 12 from one side you get -6x = -6x -12 (-12)
causing you not to be able to solve it
