Janet solved the inequality and was asked to express her answer in set notation. Determine if she made a mistake, correct the mistake if she
a
made one and create the correct expression in set notation.
-X-2<-3
-X<-1
x < -1
Set Notation: {x1 x < -1}

What is the solution to the system of the equations? x = y - 3 x + 3y = 13

This is so harddd! solve. 1 + 1 = solve 4 + 4 = solve 3 x 3
