2 - (x + 4) >= 3 - 2x
2 - x - 4 >= 3 - 2x
-x - 2 >= -2x + 3
add x to each side
-2 >= -x + 3
subtract 3 from both sides
-5 >= -x
multiply through by -1, remembering to reverse the direction of the inequality
5 <= x
means
x >= 5
for interval notation use the square bracket when = is involved and the round bracket when it is not.
