Question 318551
{{{4=5+sqrt(2x+59)}}} subtract 5
{{{-1=sqrt(2x+59)}}} square both sides
{{{1=2x+59}}} subtract 59
{{{-58=2x}}}divide by 2
{{{highlight(-29=x)}}}
<p>
checking
{{{4=5+sqrt(2x+59)}}}
{{{4=5+sqrt(2(-29)+59)}}}
{{{4=5+sqrt((-58)+59)}}}
{{{4=5+sqrt(1)}}}
{{{4=5+(-1)}}} or {{{4=5+(1)}}} this one doesnt work 4=6
{{{4=4}}}
correct
