3x + 3 (x-1) < 7 - 2x + 6

I got 2 < x.

I followed the way you showed me how to do the last one.

I would think x<2.

\(3x + 3 (x-1) < 7 - 2x + 6\\ 3x + 3x-3 < 13 - 2x\\ 6x-3 < 13 - 2x\\ 8x<16\\ x<2 \)

HANG ON HERE! when i divided i could switch the sign from < to >. isnt that how you do it?

Only if you divide by a negative number.
