Question

5 x + 2 = −10

4 x − 2 = 5 + 3 x − 6

3 − 2 x = 1

Answer 1

$5 \times + 2 = - 10$

$5 \times + 2 - 2 = - 10 - 2$

$5 \times = - 12$

$\frac{5 \times }{5} = \frac{ - 12}{5}$

$\times = \frac{ - 12}{5}$

$4 \times - 2 = 5 + 3 \times - 6$

$4 \times - 2 = - 1 + 3 \times$

$4 \times - 2 = 3 \times - 1$

$4 \times - 2 + 2 = 3 \times - 1 + 2$

$4 \times = 3 \times + 1$

$4 \times - 3 \times = 3 \times + 1 - 3 \times$

$\times = 1$

$3 - 2 \times = 1$

$- 2 \times + 1 = 1$

$- 2 \times + 3 - 3 = 1 - 3$

$- 2 \times = - 2$

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

$\times = 1$

Espero te sirva
