You can put this solution on YOUR website!
r=-3s
\n" ); document.write( "r+4s=10\r
\n" ); document.write( "\n" ); document.write( "plug in -3s into r
\n" ); document.write( "so you get -3sr + 4s =10
\n" ); document.write( "add r's up and you get 1s=10
\n" ); document.write( "s=10\r
\n" ); document.write( "\n" ); document.write( "same for next problem
\n" ); document.write( "x-y=5
\n" ); document.write( "x+2y=7\r
\n" ); document.write( "\n" ); document.write( "isolate one of the variables
\n" ); document.write( "-y=5-x
\n" ); document.write( "divide by -
\n" ); document.write( "so you get y=-5+x
\n" ); document.write( "plug in for y
\n" ); document.write( "and solve\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "p l+l+w+w or 2l+2w
\n" ); document.write( "l= w+24
\n" ); document.write( "so plug in to ^^
\n" ); document.write( "2(w +24) +2w=268
\n" ); document.write( "so you get
\n" ); document.write( "4w +48= 268
\n" ); document.write( "subtract by 48 and divide by 4
\n" ); document.write( "and you find w
\n" ); document.write( "plug in w into l+w+24
\n" ); document.write( "sorry but i didnt want to do them all if you really need help with them ill do it but next time try to do less
\n" ); document.write( " \n" ); document.write( "
\n" );
