Question

1) Resolva as equações:

a) 2x = 8

b) x - 7 = - 9

c) 3x + 1 = - 5

d) 2x + 6 = x - 7

e) 2x + 5 - x = 4x - 4

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

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

h) - 3 ( 2 - 3x ) = x + 7 + 2

i) 3 ( 5x - 7 ) = 8x - 21

j) - 4 ( - 2x + 8 ) = - 6x + 9

Answer 1

a) x = 4

b) x = -2

c) x = -2

d) x = -11

e) x = 3

f) x = 0

g) x = 10/8

h) x = 15/8
