5 - 3lp + 4l ≤ -10
Subtract 5 from both sides.
-3lp + 4l ≤ -15
Divide both sides by -3.
|p + 4| ≤ 5
p + 4 ≤ -5 or p + 4 ≥ 5
Answer is option C. p + 4 ≥ 5 or p + 4 ≤ -5

Answer:
x=101/65, y=-16/65. (101/65, -16/65).
Step-by-step explanation:
4x+9y=4
9x+4y=13
----------------
9(4x+9y)=9(4)
-4(9x+4y)=-4(13)
------------------------
36x+81y=36
-36x-16y=-52
----------------------
65y=-16
y=-16/65
4x+9(-16/65)=4
4x-144/65=4
4x=4+144/65
4x=404/65
x=(404/65)/4=101/65
x=101/65, y=-16/65.
