You can put this solution on YOUR website!
You want to use the substitution property here.


\n" ); document.write( "Get the first equation to get as to an \"x=...\" or \"y=...\"


\n" ); document.write( "So, rewrite the first equation to be in slope-intercept form. y= -x+4


\n" ); document.write( "Substitute this equation in on the second equation


\n" ); document.write( "2x-(-x+4)=5

\n" ); document.write( "Simplify:

\n" ); document.write( "3x+4=5

\n" ); document.write( "3x=1

\n" ); document.write( "x=1/3

\r
\n" ); document.write( "\n" ); document.write( "Now plug in your answer on one of the original equations.


\n" ); document.write( "(1/3) + y = 4
\r
\n" ); document.write( "\n" ); document.write( "y = 4 - (1/3)

\n" ); document.write( "y = 3\"2%2F3\"


\n" ); document.write( "Therefore:


\n" ); document.write( "x = (1/3)

\n" ); document.write( "y = 3\"2%2F3\"
