Why is first equation is x negative and in equations 2,3 & 4 answers are not negative and also sign changes?
Sign is greater than or equal to in the following equation.
Sign is less than or equal to in the answer.
In equation 1, the > cannot chamge to =
Subtract x from both sides to get
y > -x+1
In equation 2, add y-5 to both sides to get x-5 > y, thish is the same as
y < x-5
