Answer:

x=5,y=6

Step-by-step explanation:

given,  6x+2y=42................(1)

           -6x+12y=42..............(2)

adding (1) and (2)

                  6x+2y-6x+12y=42+42

                   14y=84

                     y=\frac{84}{14}

                       y=6,

y=6 put in equation (1)

6x+2times{6}=42

6x=42-12=30

x=\frac{30}{6}

x=5

What law can be used to determine that the conclusion is valid based on the given statements
ryzh [129]

Answer:

A. Law of detachment

Step-by-step explanation:

The Law of detachment implies that when one condition is fulfilled the other cannot be and vice versa, then it is made the conclusion.

This condition is made the conclusion.

The Acute and Obtuse are detached of each other.

The acute angle is one in which the value of the angle is less than 90 degrees and obtuse angle is one in which the angle is greater than 90 degrees but less than 180 degrees.

Thus angles less than 90 degrees are acute and greater than 90 degrees are obtuse.

The conclusion of the given statement  is valid based on the law of detachment as the condition has been made a conclusion.
