Question

5x -4y = -2
2x + y = -6
planteamiento y respuestas por favor

Answer 1

5x -4y= -2
X= (-2 + 4y ) / 5

2x + Y = -6
X = (-6 -Y)/2


(-2 + 4y ) / 5 = (-6 -Y)/2
(-2 + 4y )2 = (-6 -Y)5
-4 + 8y = -30 -5y
8y + 5y = -30 + 4
13y = -26
Y = -26/13
Y= -2

2x + Y= -6
2x -2 = -6
2x = -6 + 2
X= -4/2
X = -2
