Step 1To isolate for z, multiply by the reciprocal of the coefficient, which is 2:                    1                    2              x    &amp;lt;    20        2    ⋅                  1                    2              z    &amp;lt;    20    ⋅    2  Simplify both sides      z    &amp;lt;    40  This means that any value of z less than 40 will satisfy this inequality.
