Question

3x - 2 = -3 cuanto da

Answer 1

Explicación paso a paso:

1)

$3x - 2 = - 3 \\ 3x = - 3 + 2 \\ 3x = - 1 \\ x = - \frac{1}{3}$

2)

$9 - 2 = x \\ x = 7$

3)

$(x + 2) - 3 = 7 \\ x + 2 - 3 = 7 \\ x - 1 = 7 \\ x = 7 + 1 \\ x = 8$

4)

$\frac{x}{2}$

$\frac{x}{2} + 3 = 2(5 - 2) \\ \\ \frac{x}{2} + 3 = 10 - 4 \\ \\ \frac{x}{2} = 6 - 3 \\ \\ \frac{x}{2} = 3 \\ x = 2(3) \\ x = 6$

espero que sea de tu ayuda

saludos :)

Answer 2

1)

$\sf3x - 2 = - 3 \\ \sf3x = - 1 \\ \sf \boxed{x = - \frac{1}{3} }$

2)

$\sf9 - 2 = x \\ \boxed{ \sf \: x = 7}$

3)

$\sf \: x + 2 - 3 = 7 \\ \sf \boxed{ \sf \: x = 8}$

4)

$\sf \frac{x}{2} + 3 = 2(5 - 2) \\ \sf \: \frac{(x + 6)}{2} = 2 \times 3 \\ \sf \: x + 6 = 12 \\ \sf \boxed{ \sf \: x = 6}$
