Algebra.Com's Answer #55136 by bucky(2189)![]() ![]() ![]() You can put this solution on YOUR website! Let x be one of the integers. Then the other integer must be x+1 because the integers \n" ); document.write( "are consecutive. The sum of these two integers is to be 145. So we can write the equation \n" ); document.write( "for the sum as: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "On the left side you can combine the x terms to get: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Since we need to solve for x we need to eliminate the 1 on the left side by subtracting \n" ); document.write( "1 from both sides. When we subtract 1 from both sides, the equation becomes: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "And we can solve for x by dividing both sides of this equation by 2 to get: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "We now know that one of the integers is 72. The next consecutive integer is x + 1 or \n" ); document.write( "72 + 1. So the other missing integer is 73. \n" ); document.write( ". \n" ); document.write( "Check: Do the two integers 72 and 73 add up to be 145? Since they really do, we have the \n" ); document.write( "correct solution. The integers we were to find are 72 and 73. \n" ); document.write( ". \n" ); document.write( "Hope this helps you to understand the problem and find your way to the solution. \n" ); document.write( " |
