ok, the first thing we need to do it to isolate the variable.

7x+18=-24
     -18    -18
7x=-42

then divide to cancel out multiplication

7x=-42
---   ---
7      7

x=-6

7x + 18 = -24

Take 18 to the other side.
7x + 18 - (18) = -24 - (18)
7x = -42

Divide both sides by 7:
[tex] \frac{7x}{7} [/tex] = [tex] -\frac{42}{7} [/tex]
7 and 7 cancels out

x = -6
