Question 106139
It is kind boring if we use that method.

So I prefer this exciting method.


Since {{{y=-3x/4+1/4}}} and {{{y=3x/4-3/4}}}, then,

{{{-3x/4+1/4=3x/4-3/4}}}
{{{4(-3x/4+1/4)=4(3x/4-3/4)}}}
{{{-3x+1=3x-3}}}
{{{3x-3=-3x+1}}}
{{{3x+3x-3=-3x+3x+1}}}
{{{6x-3=0+1}}}
{{{6x-3=1}}}
{{{6x-3+3=1+3}}}
{{{6x+0=4}}}
{{{6x=4}}}
{{{6x/6=4/6}}}
{{{(6/6)x=4/6}}}
{{{1*x=2/3}}}
{{{x=2/3}}}

To solve for y, let's choose from the two---{{{y=-3x/4+1/4}}} and
{{{y=3x/4-3/4}}}

I choose ---{{{y=-3x/4+1/4}}} . so,

{{{y=-3(2/3)/4+1/4}}}
{{{y=(-6/3)/4+1/4}}}
{{{y=-2/4+1/4}}}
{{{y=(-2+1)/(4)}}}
{{{y=-1/4}}}
