Answer:
The correct option is 3.
Step-by-step explanation:
Given: ,
.
Prove:
(Given)
(Segment congruent postulate)
(Substitution property of equality)
Add 1 on both sides.
(Addition property of equality)
Divide both sides by 3.
(Division property of equality)
Hence proved.
The required equation for box 1 is 3x=27.
Therefore the correct option is 3.

The given term is: 
Since here, the numerator i.e.
cannot be factorized.
SO, the only excluded value is found on the basis of the denominator. The denominator should not be equal to 0, otherwise, the fraction will turn out to be zero.
SO, if y
-4, then denominator will not be zero.
Therefore, the excluded value is -4
