Question

4. Resuelve cada ecuación:
a. n – 1456 = 5089.
b. 18 – (p + 21) = 20
c. (h - 6) + 18 = 12
d. K + 2043 = 8972

Answer 1

Respuesta:

a) n - 1456=5089

n=5089 + 1456

n= 6545

b) 18 - (p + 21 )= 20

18 -( 22p)=20

18-22p= 20

-4p =20

p = 20/4

p= 5

c ) (h-6)+18=12

(-5h ) +18=12

-5h+18=12

-5h = 12-18

-5h = - 6

h= 6/5

h =1,2

d) k + 2043= 8972

k= 8972 - 2043

k = 6929
