Forces have to be added as vectors. This means that in certain cases, the forces can cancel, and in other cases they can be added.

the forces cancel each other out Huh? The forces simply add. F1x + F2x = F3x
Forces that cancel each other out are called balanced forces.
These add up to 0 -- they "cancel" each other out.
If the forces are all normal (at right angles to) the sides the resultant is 0 (they all cancel each other out ).
Add 4 to both sides to cancel out the -4. Then m will equal 22
