Question

(3x+1)+2<11 Help please

Answer 1

just solve for x

if it helps, pretend the < is an equal sign
then just replace it at the end

although if you ever multiply by -1 to both sides
then you have to switch the signs from < to > and vice versa

Answer 2

(3x+1)+2<11

3x+1+2<11

3x+3 < 11

3x +3 -3 < 11-3

3x < 8

x < 8/3

You basically simplify as much as possible. Then you follow PEMDAS in reverse to isolate x
