Question

Solving two-step inequalities -2x + 12 is less than -4 ​

Answer 1

x is greater than or equal to 4

Explanation:

`- 2x + 12 \leqslant 4 \\ subtract \: 12 \: from \: both \: sides \\ - 2x + 12 - 12 \leqslant 4 - 12 \\ - 2x \leqslant - 8 \\ x \leqslant ( - 8)/( - 2) \\ x \geqslant 4`

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