Question

resolva as seguintes equações:

a) 6x = 18
b) 3x = 2
c) 5x = -30
d) 4x = 10
e) -2x = 14
f) -8x = -2
g) 5x - 1 = 19​

Answer 1

a) 6x = 18

x = 18/6

x = 3

b) 3x = 2

x = 2/3

x = 0,66

c) 5x = -30

x = - 30/5

x = - 6

d) 4x = 10

x = 10/4

x = 2,5

e) -2x = 14

x = 14/-2

x = - 7

f) -8x = -2

x = -2/-8

x = 0,25

g) 5x - 1 = 19

5x = 19 + 1

5x = 20

x = 20/5

x = 4
