Answer:

x≤3

Step-by-step explanation:

2(4+2x)≥5x+5

Distribute.

2*4+2*2x≥5x+5

8+4x≥5x+5

Subtract 8 from both sides.

8-8+4x≥5x+5-8

4x≥5x-3

Subtract 5x from both sides.

4x-5x≥5x-5x-3

-x≥-3

Divide both sides by -1.

Note that when you divide an inequality by a negative number, you must flip the sign.

x≤3
