We can check this two ways: distributing the -0.5, and plugging in a number for x.
First, we can check this by distributing the -0.5. Our equation becomes:
-1.5x -2.5 = -1.5x + 2.5
Clearly, this is not true. We can show this one more time by plugging in a number for x. I will use 2.
Now, we evaluate both sides and see if they are equal.
-3 - 2.5 = -3 + 2.5
-5.5 = 0.5
Clearly, this is not true. These expressions are not equivalent.

He will run 4.3 miles in 36 minutes.
Step-by-step explanation:
Given,
8.3 minutes running = 1 mile distance
In one minute;
1 minute running =
After 36 minutes;
36 minutes running = 36*1 minute running distance
36 minutes =
He will run 4.3 miles in 36 minutes.
