You can put this solution on YOUR website!
here is the solution
\n" ); document.write( " multiply the first equation by 5 and the second equation by 3
\n" ); document.write( " 25x+15y=35
\n" ); document.write( " 9x-15y=-69
\n" ); document.write( " now add both of them
\n" ); document.write( " 34x=-34
\n" ); document.write( " x=-1
\n" ); document.write( "substitute x=-1in one of the equations to get value of y
\n" ); document.write( " 5x-1+3y=7
\n" ); document.write( " -5+3y=7
\n" ); document.write( " 3y=7+5
\n" ); document.write( " 3y=12
\n" ); document.write( " y=4
\n" ); document.write( "so the value of the y variable is 4
\n" ); document.write( "
\n" );
