Explanation:

6-(2x+4) is less than or equal to 10

6-(2x+4) ≤ 10

6 - 2x - 4 ≤ 10

combine like terms on left side:

2 - 2x ≤ 10

subtract 2 from both sides:

2 - 2x - 2 ≤ 10 - 2

- 2x ≤ 8

divide both sides by -2: (remember, when dividing by a negative number you must FLIP the sign direction)

- 2x/-2 ≥ 8/-2

x ≥ 8/-2

x ≥ -4

[-4, ∞)
