Question

2. Coloque V ( verdadeiro) ou F (falso),
a) 9x + 4 = - 3x-2
9x +3x = -2-4
12x = -6
x= 12/6
x= 2 )
b) 6x +2 = 9x - 5
6x +9x = -5 +2
15x = -3
x=15/-3
x=-5 ()

Answer 1

a) 9x + 4 = - 3x-2

9x +3x = -2-4

12x = -6

x= 12/6

x= 2 (Falso) x= -2

b) 6x +2 = 9x - 5 => 3x= -7

6x +9x = -5 +2 x= -7/3

15x = -3

x=15/-3

x=-5 (Falso)
