    now to get x on its own you divide by -2 from both sides

    \[-2x \ge-25+13\] add 25+13 and then divide by (-2). Don't forget to change sign into another (from \[from \ge \to l\]

    now you are not done yet whenever you have to divide or multiply by a negetive number you have to change the sign so the answer is NOT: x (> or =) 6 but it is: x (< or =) 6
