Question

2X-5(2X-4) mai mare sau egal 7-11X
REPEDE VA ROOOOG

Answer 1

$2x - 5(2x - 4) \geqslant 7 - 11x$
$2x - 10x + 20 \geqslant 7 - 11x$
$- 8x + 20 \geqslant 7 - 11x$
$- 8x + 11x \geqslant 7 - 20$
$3x \geqslant - 13$
$x \geqslant - \frac{13}{3}$

Answer 2

$2X-5\left(2X-4\right)\ge \:7-11X \\ -8X+20\ge \:7-11X \\ -8X\ge \:-11X-13 \\ -8X+11X\ge \:-11X-13+11X \\ 3X\ge \:-13 \\ X\ge \:-\frac{13}{3}$
