Question 1132519
----------
If x - y = -10, x + z = -6, and y - z = 8, Find the value of (x + y) / z.
----------



Use the last two equations and add corresponding members.
{{{(x+z)+(y-z)=-6+8}}}
{{{x+y+0=8-6}}}
{{{x+y=2}}}


Sum the corresponding members of all three equations, and find:
{{{x=-4}}}.


Second Equation, {{{x+z=-6}}}
{{{z=-6-x}}}
{{{z=-6+4}}}
{{{z=-2}}}



-

{{{(x+y)/z}}}


{{{2/(-2)}}}
