            RATE     TIME     DISTANCE
WALK         4        w        4w
JOG          8        j        8j
TOTAL                 1         6


system%28w%2Bj=1%2C4w%2B8j=6%29
The simplest way to setup the data and solve for the variables is to assign them to the TIMES, allowing you to avoid first forming rational expressions in the data analysis. The question then asks for the value of 8j.
