-2x + 6 ≤ 2

Isolate the x. Do the opposite of PEMDAS. First, subtract 6 from both sides

-2x + 6 (-6) ≤ 2 (-6)

-2x ≤ 2 - 6

-2x ≤ -4

Next, divide -2 from both sides (Remember that when dividing a negative number, flip the sign)

-2x/-2 ≤ -4/-2

x ≥ 2

x ≥ 2 is your equation.

This means that x can be equal to, or greater than 2

You're interval Notation is: [2, ∞)

hope this helps

Note: In interval notation, you use a bracket for closed, and a parenthesis for open.
