We rewrite the inequality so that it matches the left side of the "then" part.
a)By adding 8 to each side, we have: x+8>5+8
x+8>13
So, insert>.
b)Multiply both sides by -5. Recall that when we multyply of divide both sides of an inequality by a negative number, we change the direction of the inequality: -5x<-15
Add 18 to both sides: -5x+18<3
So, insert <.
