Answer 1

Resposta:

Explicação passo a passo:

a) x + 2x = 17 -5

3x = 12

x = 12/3

x = 4

b) -2x -x = 6-21

-3x = -15

x = -15/(-3)

x = 5

c) 5x + x = -9+3

6x = -6

x = -6/6

x = -1

d) -x-2x = -18-3

-3x = -21

x = -21/(-3)

x = 7

e) 2x-3x = 22 +5 -8

-x = 19

x = -19

f)-6x +2x = 6-38

-4x = -32

x = -32/(-4)

x = 7

g) 5x +2x - 10x = 3 - 1 -8

-3x = -6

x = -6/(-3)

x = 2

h) 5x - 3x = -4 +4

2x = 0

x = 0

i) 4x +x -3x = 2 + 3-5

2x = 0

x = 0
