according to the code of Mathematical Logic, there exists more properties, one of its principles is the consequence and effects property, or the so-called equivalence implicationwhich is defined as follows:Two expressions A and B are equivalent if A can produce B, and B can produce A. It means A implies B and B implies A.</span>

Step-by-step explanation:
In exercise 3 (2,6) means that x=2 and y=6
so you have to check that if this values of x and y satisfied the given equation,
by showing that the left hand side = the right hand side ..
Step-by-step explanation:
(-6x +3y=9 )×4
( 10x+4y)×3
-24x +12y =36
30x+12y= -18
-24x+12y- (30x+12y)= 36-(-18)
-54x = 54
x= -1
by using 10x +4y = -6
apply x= -1
-10+4y= -6
4y= -6 +10
4y=4
y=1
so the answer is x=-1 and y= 1
