Algebra.Com's Answer #95926 by Earlsdon(6294)![]() ![]() ![]() You can put this solution on YOUR website! Ok, start by assigning variables to the unknown quantities: \n" ); document.write( "Let B = the number of boys and G = the number of girls. \n" ); document.write( "From the problem description, you can write: \n" ); document.write( "1) G+B = 25 \"In a class of 25 students,...\" and... \n" ); document.write( "2) G = B+7 \"...there are 7 more girls than boys.\" \n" ); document.write( "Now you substitute the second equation (G = B+7) for the G in the first equation (G+B = 25) and solve for B. \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
