The 2 equations are
-2x + y = -17 ---1)
3x + y = 23 ---2)
we need to have the same coefficient for one of the variables.
Already y variable has the coefficient of 1 for both equations so we can use the equations as it is.
2) - 1) subtract 1) from 2)
3x-(-2x) + y -y = 23-(-17)
5x = 40
x = 8
substituting x = 8 in the 2nd equation
3*8 + y = 23
24 + y = 23
y = -1
solution - (8,-1)
Answer:
8 miles
Steps:
Since he is AT LEAST running 24 miles and he already ran 16. He only had 8 more miles to go. 24 miles is the minimum he is running, he could run more.

<h3>The measurement of the central angle is 135 degrees</h3>
<em><u>Solution:</u></em>
<em><u>The length of arc when angle given in degrees is given as:</u></em>
Where,
r is the radius
is the central angle in degrees
From given,
Substituting the values we get,
Thus the measurement of the central angle is 135 degrees
