Given inequality
=> −2(x+1)≥3x+8
=>
![- 2x - 2 \geqslant 3x + 8 \\ \\ add \: 2 \: in \: both \: sides \\ \\ - 2x \geqslant 3x + 10 \\ \\ subtract \: with \: - 3x \: in \: both \: sides \: \\ \\ - 5x \geqslant 10 \\](https://tex.z-dn.net/?f=%20-%202x%20-%202%20%5Cgeqslant%203x%20%2B%208%20%5C%5C%20%5C%5C%20add%20%5C%3A%202%20%5C%3A%20in%20%5C%3A%20both%20%5C%3A%20sides%20%5C%5C%20%5C%5C%20-%202x%20%5Cgeqslant%203x%20%2B%2010%20%5C%5C%20%5C%5C%20subtract%20%5C%3A%20with%20%5C%3A%20-%203x%20%5C%3A%20in%20%5C%3A%20both%20%5C%3A%20sides%20%5C%3A%20%5C%5C%20%5C%5C%20-%205x%20%5Cgeqslant%2010%20%5C%5C%20)
now multiply with - on both sides.
As we know now sign will change
=> 5x >_ -10
Now divide by 5 on both sides
=> x >_ -2
HOPE IT HELPED YOU.
