How do you solve this 3x-4=3x-5
Basile [38]
Combine like terms so 3x + 3x= 6x
Then put the minus signs with the 4 and 5 and add them together so -4+ -5= -9
Now you have 6x=-9 So you divide by 6 on both sides canceling out 6
but 9 divided by 6 doesn't go into a specific number therefore it has no solution which is a possible answer
