Answer

[-9,9]

Work Step by Step

First, multiply both ends of the inequality by 2 to cancel out the 2. Then subtract each side by 1 to get x by itself. Because the signs are less/greater than or equal to, x is or in between -9 and 9, and the brackets indicate that. -4$\leq$$\frac{x+1}{2}$$\leq$5 -8$\leq$$x$+1$\leq$10 -9$\leq$$x$$\leq$9 [-9,9]
