The most efficient way to solve this problem is isolating the y in the first equation because:
6x + 3y = 27
3y = 27 - 6x
y = 9 - 2x
Since all the numbers have a common factor of 3, it can be easily simplified/reduce.
If you used any other variable, you would have gotten a fraction.
Now that you found y, you can substitute it into the other equation to solve for x.
ANYWAYS, your answer is A

Step-by-step explanation:
25
The diagonals of a kite are perpendicular to each other, hence
∠EHF = 90°
The sum of the 3 angles in a triangle = 180°
In ΔEHF
∠1 + ∠2 + 90 = 180, that is
42 + ∠2 + 90 = 180
132 + ∠2 = 180 ( subtract 132 from both sides )
∠2 = 48°
26
DE and DG are congruent sides, hence
4x - 2 = 22.5 ( add 2 to both sides )
4x = 24.5 ( divide both sides by 4 )
x = 6.125
27
∠A and ∠C are congruent, hence
∠A = ∠C = 82°
The sum of the interior angles of a kite = 360°, hence
x = 360 - (82 + 82 + 140) = 360 - 304 = 56
The difference between 6 and -11 is 17
because 6 - (-11) = 17
