How do I solve -2<3y+1≤10?

Im not sure how to go about solving -2<3y+1≤10

You don't have to use the same numbers etc. to show me how it works, I just want to know how to get started, I'm not fishing for the actual answer. Otherwise I would see Bob.

    Treat it like two seperate equations, so -2<3y+1 and 3y+1≤10

    Then get all number on one side and ys on the other side.

    You said you didn't want the actual answer but here it is in case you still get stuck. I haven't separated anything here, that was just to make it easier for you to see initially.

    -2<3y+1≤10 subtract 1 from all parts

    -3<3y≤9 divide through by 3

    - 3 < 3y < 9

    - 1 < y < 3

    i personally find it easier to deal with these inequalities by dealing with them separately like normal equations.

    e.g., first i take



    or y>-1

    then the 2nd 1



    i.e y<=3

    then combining the 2 results, -1<y<=3

    subtract one


    divide by 3



    so y is between -1 and 3

    treat like an equation 3y+1=10 then find for y

    -2<3y+1<_10 add -1 both sides -2-1<3y<_10-1 -3<3y <_9 , divided by 3 , -1<y<-3
