Algebra.Com's Answer #730574 by addingup(3677)![]() ![]() You can put this solution on YOUR website! x + y = 35 subtract x from both sides: y = 35 - x \n" ); document.write( "108x + 340y = 8,188 in this equation substitute for y: \n" ); document.write( "108x + 340(35 - x) = 8,188 \n" ); document.write( "108x + 11,900 - 340x = 8,188 \n" ); document.write( "-232x = -3,712 divide both sides by -232, and remember -/- = + \n" ); document.write( "x = 16 \n" ); document.write( "Howard bought 16 boxes of wrenches and 35-16 = 19 boxes of hammers \n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ \n" ); document.write( "Check: \n" ); document.write( "16(108) + 19(340) = 8,188 Correct \n" ); document.write( " |
