K) X/3= 7
L) 2x/5= 4
M) 2x/3= -10​

Answer 1

Resposta:

A) x + 5 = 8

x=3

B) x - 4 = 3

x=7

C) x + 6 = 5

x= -1

D) X-3 = -7

x=10

E) + 9 = -1

x= -10

F) X + 28 = 11

x= -17

G) x - 109 = 5

x=114

H) 7(x - 5) = 3 (x + 1)

x=19/2

1) 3 (x - 2) = 4 (-x + 3)

x=18/7

J) 13 + 4(2x - 1) = 5 (x+2)

x=1/3

K) X/3= 7

x=21

L) 2x/5= 4

x=10

M) 2x/3= -10

x= -15
