Question

resolva as sequintes equações (b)4x=-27 (c)3x-2=3 (d)3x-9=0 (e)-2x-1=x-4 (f)-2x-18=0​

Answer 1

Resposta:

Explicação passo-a-passo:

b) 4x = -27

x = -27/4

c) 3x - 2 = 3

3x = 3 + 2

x = 5/3

d) 3x - 9 = 0

3x = 0 + 9

x = 9/3

x = 3

e) -2x -1 = x - 4

-2x = x - 4 + 1

-2x - x = -3

-3x = -3

x = 3/3

x = 1

f) -2x - 18 = 0

-2x = 18

x = 18/-2

x = -9
