Question

punctele e, f si g mulțumesc anticipat :D e urgent ​

Answer 1

e)

$\frac{x}{2} - \frac{x}{3} = 2 \times 3$

$\frac{x}{2} - \frac{x}{3} = 6$

$3x - 2x = 36$

$x = 36$

f)

$- 3 \times (x + 1) = 2 \times (x + 6)$

$- 3x - 3 = 2x + 12$

$- 3x - 2x = 12 + 3$

$- 5x = 15$

$x = - 3$

g)

$\frac{x - 1}{2} + \frac{3}{4} = \frac{x - 5}{6} + \frac{1}{12}$

$6(x - 1) + 9 = 2(x - 5) + 1$

$6x - 6 + 9 = 2x - 10 + 1$

$6x + 3 = 2x - 9$

$6x - 2x = - 9 - 3$

$4x = - 12$

$x = - 3$
