You can put this solution on YOUR website!
X/2 + 2y =9 --> multiply it by 4, because i do not want to work with fractions.
\n" ); document.write( "2x-y = 18\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2x + 8y = 36
\n" ); document.write( "2x - y = 18\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Subtract the 2 equations, to give 9y = 18
\n" ); document.write( "so y = 18/9
\n" ); document.write( "y = 2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Hence, 2x-2 = 18
\n" ); document.write( "2x = 20
\n" ); document.write( "so x = 20/2
\n" ); document.write( "x = 10\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "check in other equation: 10/2 + 2(2)
\n" ); document.write( "5 + 4
\n" ); document.write( "--> 9 which is the correct answer for that equation.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so my answers are correct.\r
