  1. The Subject Area looks like math? What is the "a" for in -4a? A minus number will be less than zero so what do you think?

  2. -4a <or= 6.5
    4a >or= -6.5
    (The sign direction must switch when multiplying both sides by a negative number, -1). Now divide both sides by 4.
    a >or= -1.625
