Answer 1

Respuesta:

Explicación paso a paso:

a. m + 18 = –29

m= -29-18

m = -47

b. t – 32 = –47

t = -47+32

t = -15

c. x – (–47) = 76

x+47 = 76

x= 76-47

x= 29

d. 56 + y = –19

y=-19-56

y= -75

e. –97 + p = 74

p=74+97

p= 171

f. 63 + g = –17

g=-17-63

g= -80

g. h – 14 = 19

h=19+14

h=33

h. n – (–87) = –52

n+87=-52

n=-52-87

n= - 139

i. –30 – k = –50

-30+50=k

20=k

k=20

j. 75 – f = 95

75-95=f

-20=f

f= - 20
