If the distance is 1.5 from -2, then it could be 1.5 less than -2 or 1.5 more than -2, so we know that we will have two points on the number line.
Let’s first find 1.5 less than -2
We will subtract 1.5 from -2
-2-1.5 = -3.5
Our first value of n will be -3.5
Next let’s find 1.5 more than -2
We will add 1.5 to -2
-2+1.5 = -0.5
Our second value of n will be -0.5
Our answers will be -3.5 and -0.5
