I am in Intro to Logic and I cannot for the life of me figure out these 4 problems. Can someone please help me out??? I am using symbles where I can, bit I need to use words for others.

1) Without using Disjunctive Syllogism

M v W

~W

There-for M

2) Without using absorption

A > (A and D)

there-for A > D

3) T if and only if (L > K)

~N and K

there-for T

4) Without the Distjunctive form of Equiv

M and W

There-for M if and only if W
