d) -3x = 10
e) -5x = -12
f) - 4x = 8
g) -3x = -9
h) -5x = 15
i) -2x = -10
j) 15 = -3x
k) -40 = -5x​

Answer 1

Resposta:

a) -X= 9  = X = -9

b) - X= -2  = X = 2

c) -7x = 14  = X = -2

d) -3x = 10  =  X = -3,33

e) -5x = -12  = X = 2,4

f) - 4x = 8  = X = -2

g) -3x = -9  = X = 3

h) -5x = 15  = X = -3

i) -2x = -10  = X = 5

j) 15 = -3x  = X = -5

k) -40 = -5x​ = X = 8
