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, ∞)
