Hola, necesito ayudaaa, por favor :( les agradeceria mucho

EJERCICIOS de Ecuaciones lineales


1. 4( 2x + 3) = 4( 6 - 3x)

2. 6(x – 3) = 10 – x

3. 3x + 12 = 2(x +12)

4. 2 – 6(2 – x) = 6 + 3(3x - 4)

5. 4( 2x + 3) = 4( 6 - x)

6. 2(3X - 2) = 2X + 6

Answer 1

Respuesta:

$8x + 12= 24 - 12x \\ 20x = 12 \\ x = \frac{12}{20}$

$6x - 18 = 10 - x \\ 7x = 28 \\ x = 4$

$3x + 12 = 2x + 24 \\ x = 12$

$2 - 12 + x = 6 + 9x - 12 \\ 8x = - 4 \\ x = - \frac{1}{2}$

$8x + 12 = 24 - 4x \\ 4x = 12 \\ x = 3$

$6x - 4 = 2x + 6 \\ 4x = 10 \\ x = \frac{10}{4} = 2.5$
