Answer 1

Verified answer

Respuesta:

Explicación paso a paso:

     1.        3(x - 2) - 1 = -5

Por propiedad distributiva:

3(x) - 3(2) - 1 = -5

3x - 6 - 1 = -5

3x - 7 = -5

3x = -5 + 7

3x = 2

      2.     4(x + 1) - 2(x + 3) = x

Por propiedad distributiva:

4(x) + 4(1) - 2(x) - 2(3) = x

4x + 4 - 2x - 6 = x

2x - 2 = x

2x - x = 2

Answer 2

Respuesta:

1.  -3 (x-2) -1 + 1 = -5+1

= -3 (x-2) = -4

= [tex]\frac{-3(x-2)}{-3}[/tex] = [tex]\frac{-4}{-3}[/tex]

= x-2 = [tex]\frac{4}{3}[/tex]

= x = [tex]\frac{10}{3}[/tex]

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

= -6x = x + 10

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

= -7x = 10

= [tex]\frac{-7x}{-7}[/tex]= [tex]\frac{10}{-7}[/tex]

= x = -[tex]\frac{10}{7}[/tex]
