Answer 1

Respuesta:

1.  x = -1.

2. x = 3.

Explicación paso a paso:

1.

6(3x-1) - 2x = 2(2x-5)-8

6(3x) +6(-1) -2x = 2(2x) +2(-5) -8

18x - 6 - 2x = 4x - 10 - 8

16x - 6 = 4x - 18

16x - 4x = -18 + 6

12x = -11

x = $\frac{-12}{12}$

x = -1

-----------------

2.

$\frac{2x}{3} - \frac{5}{2} = 1 - \frac{x}{2} \\\frac{2x(2) -5(3)}{3(2)} = \frac{1(2)-x}{2}\\ \frac{4x-15}{6} = \frac{2-x}{2} \\ 2(4x-15)=6(2-x)\\8x - 30 = 12 - 6x\\8x + 6x = 12 + 30\\14x = 42\\x = \frac{42}{14} \\x = 3$

Answer 2

Respuesta:

1. x = -1

2. x = 3

Explicación paso a paso:

1.

6(3x - 1) - 2x = 2(2x - 5) - 8

18x - 6 - 2x = 4x - 10 - 8

18x - 2x - 4x = 6 - 10 - 8

12x = -12

12x ÷ 12 = -12 ÷ 12

x = -1

2.

2x/3 - 5/2 = 1 - x/2

2x/3 + x/2 = 5/2 + 1

4x/6 + 3x/6 = 15/6 + 6/6

7x/6 = 21/6

7x/6 × 6 = 21/6 × 6

7x = 21

7x/7 = 21/7

x = 3
