Algebra.Com's Answer #372553 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! let n = \"the number\" \n" ); document.write( ": \n" ); document.write( "Just write an equation for what it says: \n" ); document.write( "\"multiply it by 7 and add 1. I get the same answer if I multiply by 2 and add 161. \" \n" ); document.write( "7n + 1 = 2n + 161 \n" ); document.write( "7n - 2n = 161 - 1 \n" ); document.write( "5n = 160 \n" ); document.write( "n = 160/5 \n" ); document.write( "n = 32 \n" ); document.write( ": \n" ); document.write( "Prove this to yourself, substitute 32 for n in the original equation \n" ); document.write( ": \n" ); document.write( "Not that hard to understand, is it! \n" ); document.write( " |
