−3x+3<6

Subtract 3 from both sides.

−3x+3−3<6−3

−3x<3

Divide both sides by -3.

−3x−3<3−3

x>−1

-3x + 3 < 6

First, subtract 3 from both sides. / Your problem should look like:
-3x \ \textless \ 6 - 3
Second, subtract 6 - 3 to get 3. / Your problem should look like:
-3x \ \textless \ 3
Third, divide both sides by -3. / Your problem should look like:
x \ \textgreater \ (3)/(-3)
Fourth, simplify
(3)/(-3) to
- (3)/(3) / Your problem should look like:
x \ \textgreater \ -(3)/(3)
Fifth, cancel 3. / Your problem should look like:
x \ \textgreater \ -1

Answer:
x \ \textgreater \ -1
