First step. Subtract 8 form both sides 3s+8-8=29-8. 3s=21. Then divide both sides by 3. 3s/3=21/3. s=7
To solve, we must do inverse operation.

Do inverse operation and apply to both sides of the equation.
3s+8=29
    -8   -8
3s=21

Now we must do the inverse operation of multiplication, which is division.
3s=21
3s/3=21/3
s=7

We are left with s=7

Our final answer s=7

Now we must check our work by plugging the answer into our equation.

3(7)+8=29
21+8=29
CORRECT ANSWER! :P
