Let's call the integer N. Then the next consecutive integer is one more than N or it is N+1.
\n" ); document.write( ".
\n" ); document.write( "Now you are told to add 1/2 of the integer N (which is N/2) to 1/5 of the next consecutive integer. And 1/5 of the next consecutive integer is (1/5)*(N+1). This sum is to equal 17. In equation form this relationship is:
\n" ); document.write( ".
\n" ); document.write( "\"N%2F2+%2B+%281%2F5%29%2A%28N%2B1%29+=+17\"
\n" ); document.write( ".
\n" ); document.write( "Get rid of the denominators by multiplying all terms in this equation by 10, a common denominator of 2 and 5, to get:
\n" ); document.write( ".
\n" ); document.write( "\"10%2AN%2F2+%2B+%2810%2F5%29%2A%28N%2B1%29+=+10%2A17\"
\n" ); document.write( ".
\n" ); document.write( "Divide the integer in each denominator into the integer in the corresponding numerator and the equation becomes:
\n" ); document.write( ".
\n" ); document.write( "\"5%2AN+%2B+2%2A%28N%2B1%29+=+10%2A17\"
\n" ); document.write( ".
\n" ); document.write( "Do the distributed multiplication on the left side and the multiplication on the right side to get:
\n" ); document.write( ".
\n" ); document.write( "\"5%2AN+%2B+2%2AN+%2B+2+=+170\"
\n" ); document.write( ".
\n" ); document.write( "Add the two terms containing N:
\n" ); document.write( ".
\n" ); document.write( "\"7%2AN+%2B+2+=+170\"
\n" ); document.write( ".
\n" ); document.write( "Get rid of the 2 on the left side by subtracting 2 from both sides:
\n" ); document.write( ".
\n" ); document.write( "\"7%2AN+=+168\"
\n" ); document.write( ".
\n" ); document.write( "Solve for N by dividing both sides by 7:
\n" ); document.write( ".
\n" ); document.write( "\"N+=+24\"
\n" ); document.write( ".
\n" ); document.write( "Then if N is 24, the next consecutive integer is 25, and those are the two integers asked for in the problem ... namely 24 and 25.
\n" ); document.write( ".
\n" ); document.write( "Check: 1/2 of N is 12, and 1/5 of N+1 is 5. If you add those two integers together, you do get 17 as is specified in the problem.
\n" ); document.write( ".
\n" ); document.write( "Hope that helps you to understand this problem.
