c) 2
Penjelasan dengan langkah-langkah:
mencari nilai x 》metode eliminasi
2x - 3y = 2 x1
3x - y = 10 x3
=
2x - 3y = 2
9x - 3y = 30
----------------- –
-7x = -28
x = 4
mencari nilai y 》metode subtitusi
2(4) - 3y = 2
8 - 3y = 2
-3y = -6
y = 2
nilai (x, y) = (4, 2)
-a² + (-b)² / (x - y)³
= -3² + (-5)² / (4 - 2)³
= -9 + 25 / 2³
= 16 / 8
= 2
