Algebra.Com's Answer #174931 by jsmallt9(3758)![]() ![]() ![]() You can put this solution on YOUR website! Solving this problem requires more logic than Algebra. The key is to recognize that 17 is a prime number. And the only factors a prime number has are 1 and itself (or -1 and the negative of itself. But the problem says B and C are positive so we will ignore the negatives.) \n" ); document.write( "So B and (B-C) must be 1 and 17. We just have to figure out which is which. Since B and C are positive, B must be larger than (B-C). So \n" ); document.write( "B = 17 and (B-C) = 1 \n" ); document.write( "And we can solve this for C: \n" ); document.write( "(17-C) = 1 \n" ); document.write( "17 = 1 + C \n" ); document.write( "16 = C \n" ); document.write( "So B = 17 and C = 16. \n" ); document.write( " |
