Question

determine a solução:

g) 10 + ( x - 2) = 5 - (x + 4)

h) 2x + (5 - x) = 3 - 3x + 6

i) 4 ( x - 2) - 2 (x + 1) = 4

j) 10 (x + 1) - 6 = 2 (x - 3) - 10

k) 2 (x - 2) + 3 ( 2 x + 2) = -5 (2 - x)

me ajudem!!!​

Answer 1

Resposta:

g) 10 + ( x - 2) = 5 - (x + 4)

10 + x - 2 = 5 - x - 4

x + x = 1 - 8

2x = -7

x = -7/2

h) 2x + (5 - x) = 3 - 3x + 6

2x + 5 - x = 3 - 3x + 6

x + 3x = 9 - 5

4x = 4

x = 4/4

x = 1

i) 4 ( x - 2) - 2 (x + 1) = 4

4x - 8 - 2x - 2 = 4

2x = 4 + 10

x = 14/2

x = 7

j) 10 (x + 1) - 6 = 2 (x - 3) - 10

10x + 10 - 6 = 2x - 6 - 10

10x - 2x = -16 - 4

8x = -20

x = -20/8

x = -10/4

k) 2 (x - 2) + 3 ( 2 x + 2) = -5 (2 - x)

2x - 4 + 6x + 6 = -10 + 5x

8x - 5x = -10 - 2

3x = -12

x = -12/3

x = -4

Espero Ter Ajudado !!
