The number of miles covered every evening obtujwd using a <em>system of equation</em> is 15 miles.
<u>Let the number of miles per evening</u> = m
- Number of miles per morning = 8 miles
- Total miles covered = 115 miles
<u>Using the expression below :</u>
<em>Number of days(miles per morning + miles per evening) = 115 miles </em>
5(8 + m) = 115
40 + 5m = 115
5m = 115 - 40
5m = 75
m = 75 / 5
m = 15 miles
Therefore, the Number of miles covered per evening is 15 miles.

7.5x + 40 = 70
Note the equal sign. What you do to one side, you do to the other. Isolate the x. Do the opposite of PEMDAS.
First subtract 40 from both sides
7.5x + 40 (-40) = 70 (-40)
7.5x = 70 - 40
7.5x = 30
Next, divide 7.5 from both sides
7.5x/7.5 = 30/7.5
x = 30/7.5
x = 4
