You can put this solution on YOUR website!
first equation is -2x + y = 2
\n" ); document.write( "second equation is x + 5 = 1
\n" ); document.write( "subtract 5 from both sides of the second equation and leave the first equation as is to get:
\n" ); document.write( "-2x + y = 2
\n" ); document.write( "x = -4
\n" ); document.write( "replace x with -4 in the first equation to get:
\n" ); document.write( "-2*-4 + y = 2
\n" ); document.write( "simp;lify to get:
\n" ); document.write( "8 + y = 2
\n" ); document.write( "subtract 8 from both sides of the equation to get:
\n" ); document.write( "y = 2 - 8
\n" ); document.write( "solve for y to get:
\n" ); document.write( "y = -6\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you have x = -4 and y = -6.
\n" ); document.write( "replace the origijnal 2 equations with those values to see if they hold true.
\n" ); document.write( "-2x + y = 2 becomes -2 * -4 - 6 = 2 which becomes 2 = 2.
\n" ); document.write( "x + 5 = 1 becomes -4 + 5 = 1 which becomes 1 = 1.
\n" ); document.write( "both equations are true.
\n" ); document.write( "solution is good.
\n" ); document.write( "solution is that x = -4 and y = -6.\r
