    A = {\[{x:-2\le x-1\le4,x \in R} \]} and B = {\[x: -5 \le x-1 \le 2, x \in R\]} Represent A-B on a number line.

    \[A=\{x:-2\le x-1\le4,x \in R\}\] solve for x get \[A=\{x:-1\le x-1\le5,x \in R\}\]

    that was wrong, solve for x get \[A=\{x:-1\le x\le5,x \in R\}\]

    It should be (3,5) because A is (-1,5) and B is (-4,3) |dw:1331393158512:dw| Just cancel out the common part. Did u get it from the figure?
