Hello,
\n" ); document.write( "Let's set up an equation first. We'll let x be the first even number.
\n" ); document.write( "Then we can say x+2 would be the next even number, Right? Well, the next even number would be x+4. So let's add all those together like this:\r
\n" ); document.write( "\n" ); document.write( " x+x+2+x+4=174\r
\n" ); document.write( "\n" ); document.write( "We're almost there. This equation could be written as:\r
\n" ); document.write( "\n" ); document.write( " 3x + 6 = 174\r
\n" ); document.write( "\n" ); document.write( "Subtract 6 from both sides gives us:
\n" ); document.write( "
\n" ); document.write( " 3x = 168\r
\n" ); document.write( "\n" ); document.write( "Divide both sides by 3 gives us:\r
\n" ); document.write( "\n" ); document.write( " x = 56 \r
\n" ); document.write( "\n" ); document.write( "Therefore the first number is 56.
\n" ); document.write( "Check it out. Does 56 + 58 + 60 = 174
\n" ); document.write( "Yep it does. \r
