Thank you. But I am not understanding how you came to that answer. This is my first algebra class I am taking, and I am so confused. Can you you explain a little to me of how you got this ?? Where did the -2x come from??
Answered by Ms. Sue
4x+7<6x+19

4x - 6x + 7 - 7 < 6x - 6x + 19 - 7

-2x < 12

Answered by TRACY
So first you put the x numbers together, but why do yu out the -7 on both sides? then you took the 4x-6x to get the 2x and took 19-7 to get the 12?? Why woudl nto take the 6x-6x and get the 0
Answered by Ms. Sue
You need to get the unknowns on one side and the knowns on the other side. To do that you subtract or add from both sides of the equation.

You do get 0 when you subtract 6x - 6x.
