Question 162649
Assume the problems is:
{{{((x-y))/((x+y))}}} = {{{4/5}}}
:
From this we can say:
x - y = 4
x + y = 5
---------------adding eliminates y, find x
2x = 9
x = {{{9/2}}}
x = 4.5
:
Find y using x + y = 5
4.5 + y = 5
y = 5 - 4.5
y = .5
:
Check solution in original equation:
{{{((4.5-.5))/((4.5+.5))}}} = {{{4/5}}}
{{{4/5}}} = {{{4/5}}}
