An implication 
is true if either the premise 
is false, or both the premise and conclusion 
are both true, and false otherwise.
Negation 
is straightforward; if a statement is true, then its negation is false, and vice versa.
A conjunction 
is true if both premises are true, and false otherwise.
Finally, by the rules of implication, we can fill the last column:
X/35 = 7
we can multiply 35 on both sides
x = 245
