Question

- 5x _< 3x -2????
preciso dos cálculos
- 2x - 3 > 1??
6x - 4 _> 2x - 9??

Answer 1

-5x ≤ 3x - 2
-5x - 3x ≤ -2
-8x ≤ -2
x ≥ ¹/₄


-2x - 3 > 1
-2x > 4
x < - 2


6x - 4 ≥ 2x - 9
6x - 2x ≥ - 9 + 4
4x ≥ -5
x ≥ ⁻⁵/₄

Answer 2

$-5x \leq 3x-2$
$-5x-3x \leq -2$
$-8x \leq -2$
$8x \geq 2$
$x \geq \frac{2}{8}$

$-2x-3\ \textgreater \ 1$
$-2x\ \textgreater \ 1+3$
$-2x\ \textgreater \ 4$
$2x\ \textless \ -4$
$x\ \textless \ \frac{-4}{2}$
$x\ \textless \ -2$

$6x-4 \geq 2x-9$
$6x-2x \geq -9+4$
$4x \geq -5$$x \geq \frac{-5}{4}$
