**Anonymous**, Thursday, August 23, 2012 at 2:02amLet x be the number of miles run by Jan.

Let x be the number of miles run by Mya.

Let x-8 be the number of miles run by Sara.

* using the following equations, we have:

x+x+x-8=64

3x-8=64

3x=64+8 * since we transposed -8 on the right side, it became +8.

3x=72 * in order to get the value of x, we divide both side by 3.

x= 24 miles.

Jan and Mya ran 24 miles each while Sara, x-8 (24-8), run 16 miles.

If we add the 3 numbers, 24 mi, 23 mi, and 16 mi, the total will be 64 miles.
