Answer:

x is greater than or equal to 4

Step-by-step explanation:

[tex] - 2x + 12 \leqslant 4 \\ subtract \: 12 \: from \: both \: sides \\ - 2x + 12 - 12 \leqslant 4 - 12 \\ - 2x \leqslant - 8 \\ x \leqslant \frac{ - 8}{ - 2} \\ x \geqslant 4[/tex]

Note: when you divide both sides by a negative, the sign flips.
