A.156\x=13 B. x\(-15)=11 C.741/(-21)=X D.-(21/7)=X

Answer 1

156/x=13
156=13x
x=156/13
x=12

x/-15=11
x=11(-15)
x=-165

741/-21=x
x=-35.3

21/7=x
x=3

Answer 2

Despejando "x"

A=

156 / x = 13

x= 156 / 13

x=12

B)

x / (-15) = 11

x = 11 . (-15)

x= - 165

C)

x = 741 / (-21)

x= -247 / 7

D)

x = -(21/7)

x= -3
