Question

1 Resuelvo las siguientes ecuaciones 3. :-*​

Answer 1

Explicación paso a paso:

a) 3x + 1 = x - 1

3x - x = - 1 - 1

2x = -2

x = -1

b) 5(2x + 3) = 5x + 8

10x + 15 = 5x + 8

10x - 5x = 8 - 15

5x = -7

[tex]x = - \frac{7}{5} [/tex]

c)

[tex] \frac{3}{4}x - 4 = 2x + \frac{1}{2} [/tex]

[tex]3x - 16 = 8x + 2[/tex]

[tex]3x - 8x = 2 + 16[/tex]

[tex] - 5x = 18[/tex]

[tex]x = - \frac{18}{5} [/tex]
