Isolate x. First add 10 to both sides
8x=x+21
Then subtract x from both sides
7x=21
Then divide both sides by 7
x=3
Final answer: x=3
-2.5 and -4.5 go in the left box because they are less than -2. -.5 and .5 go in the middle box because they are greater than-2 but less than 1. 1.5 and 4 go in the right box because they are greater than 1
