Question

Tipo 4

1- Resolva as equações

a) X -3= -5


b) X +4= -3


c) 2x= -8


d) -4x = -3


e) 2x -4= -8


f) -3x -3 = -12


g) 3x -4= X -6


h) 5x -8= 4x -3

Tipo 5

a) 2 × (X + 5) = × ( X -1)

b) -3 × (X -4)= 2 × (X +6)

Answer 1

a) X -3 = -5. b) X + 4 = -3
X = -5 +3. X = -3-4
X = -2. X =-7

c) 2x = -8. d) -4x = -3
X = -8/2 X = ¾
X = -4.

e) 2x -4 = -8. f) -3x -3 = -12
2x = -8+4. -3x = -12+3
2x = -4. -3x = -9
X = -4/2. X = 9/3
X = -2. X = 3

g)
