Hi,
-(x-4) ≥ 4 OR
x-4 ≤ -4 |Note: change of the direction of the Inequality when multiplying thru by -1
x ≤ 0
-3x > 9 OR
x < -3 |Note: change of the direction of the Inequality when dviding thru by -3
4x > 12
x > 3 |Multiplying or dividing thru with a positve number does NOT change the direction of the Inequality
