Question 937556
TWO equation in ONE unknown variable.  Pick either equation and solve!


{{{abs(x+7)=2}}}
either {{{-x-7=2}}}, {{{x+7=-2}}}, {{{highlight(x=-9)}}}
OR
{{{x+7=2}}}, {{{highlight(x=-5)}}}.


Then, the other equation:
{{{x(x+2)=15}}}, after division by 2 on both sides.
{{{x^2+2x-15=0}}}
{{{(x-3)(x+5)=0}}}
{{{highlight(x=3)}}} OR {{{highlight(x=-5)}}}


The value which satisfies BOTH equations is {{{highlight(highlight(x=-5))}}}.
