Transcript of valor de x y
Hallar el valor de x ; y para que exista la igualdad de pares ordenados a) (3x ; 4) = (9 ; y 5) b) ( x + 1 ; 5) = (6 ; y + 2) c) ( ; d) ( ) = (6 ; 1) ; 1) = (2 ; )
e) (-5 ; 2y) = (x+1 ; 10)
Solucin a) (3x ; 4) = (9 ; y 5)3x = 9 4 = y-5 x=3 y=9
b) ( x + 1 ; 5) = (6 ; y + 2)x+1 =6 y+2=5 x=5 y=3
c) (6 = =1
;
) = (6 ; 1)x = =y x=1 y=3
d) (=2 =1
; 1) = (2 ;x = 8-1 y = 4+2
)x=7 y=6
e) (-5 ; 2y) = (x+1 ; 10)x+1 = -5 2y= -10 x = -5-1 y= x=-6 y=-5
