Algebra.Com's Answer #681108 by addingup(3677)![]() ![]() You can put this solution on YOUR website! s+v = 130 subtract s from both sides: v = 130-s \n" ); document.write( "Next: \n" ); document.write( "4.50s+6.50v = 617 substitute for v: \n" ); document.write( "4.50s+6.50(130-s) = 617 \n" ); document.write( "= 4.50s+845-6.50s = 617 \n" ); document.write( "= -2s = -230 divide both sides by -2, and remember -/- = + \n" ); document.write( "s = 115 \n" ); document.write( "115 students showed up. \n" ); document.write( " |
