Question 77563
{{{abs(14-2z)=16}}} This expression is equivalent to:


{{{14-2z=16}}} or {{{14-2z=-16}}}


{{{cross(14-14)-2z=16-14}}} or {{{cross(14-14)-2z=-16-14}}} Subtract 14 from both sides


{{{cross(-2/-2)z=2/-2}}} or {{{cross(-2/-2)z=-30/-2}}} Divide both sides by -2

So we have the solutions of


{{{z=-1}}} or {{{z=15}}}
