Given: 5 > x + 7.
choose the solution set.
{xixer, x> -2)
{xixer, x< -2)
{xixer, x> 2]
. xixer, x< 2}

x<-2

original: 5 > x + 7

first step-subtract 7 from both sides so x is alone: 5 - 7 > x

second step-simplify: -2 > x

remember to treat the inequality sign as an equal sign. so whatever you do to one side, you have to do to the other side.
