1) Let's solve that step by step:
-3 (x - 2) > 24 Distribute the factor
-3x +6 > 24 Subtract 6 from both sides
-3x >24 -6
-3x > 18 Divide by -3, swap the sign
x < -6
2) Since the solution is any number lesser than -18on the number line we can state the possible solutions as -9 and -15 because -9< -6 and -15 < -6
