Question

Relaciona cada ecuación con su solución

a. 5 + x = 0 ( ) 27
b. -17 + x = 0 ( ) -5
c. 30 + x = 0 ( ) 17
d. x + (-27) = 0 ( ) 30
e. x + (-30) = 0 ( ) -30

Answer 1

Respuesta:

(d.)

(a.)

(b.)

(e.)

(c.)

Explicación:

a. 5 + x = 0

x = -5

b. -15 + x = 0

x = 15

c. 30 + x = 0

x = -30

d. x + (-27) = 0

x - 27 = 0

x = 27

e. x + (-30) = 0

x - 30 = 0

x = 30
