Question

t) 2.(x - 2) + 5.( 2 - X) + 6.(x + 1)= 0
u) 3. (x - 2) - (1 - x) = 13
v) X- (x + 1) = 12 - (3x - 2)
x)x12 = 1213​

Answer 1

Resposta:

Explicação passo-a-passo:

t) 2x - 4 + 10 - 5x + 6x +6 = 0

3 x = 12

x = 4

u) 3x - 6 - 1 + x = 13

2x = 13 + 6 + 1

2x = 20

x = 10

v) x - x - 1 = 12 - 3x + 2

3x = 15

x = 5

x) 12x = 1213

x= 101,083
