Question 91933
{{{y = -x +5}}}
{{{y = 2x - 4}}}
One way to solve it is to use substitution.  Set the 2 y's equal to each other.
{{{-x+5=2x-4}}}
{{{-x+x+5=x+2x-4}}}
{{{5=3x-4}}}
{{{5+4=3x-4+4}}}
{{{9=3x}}}
{{{9/3=3x/3}}}
{{{3=x}}}
Now let x=3 in one of the equations and solve for y:
{{{y=-3+5}}}
{{{y=2}}}
The solution, (x,y)=(3,2)
Happy Calculating!!!
