5x−19≤1
Add 19 to both sides, then divide by 5.
−4x+3<−6
Subtract 3 from both sides, then divide both sides by -4. Remember that negative divided by/multiplied by a negative = a positive.

5x−19≤1 OR −4x+3<−6
5x ≤ 20 OR -4x < -9
x ≤ 4 OR x > 9/4
Draw a sketch on a number line and you will see that
the solution is set of all numbers, since OR implies you want
the Union of the two sets.
