Algebra.Com's Answer #244188 by nerdybill(7384)![]() ![]() You can put this solution on YOUR website! You must apply the \"order of operations\" (PEMDAS): \n" ); document.write( "B-9[B-8(4-B)]=608 \n" ); document.write( "Distribute the -8 to terms inside parenthesis: \n" ); document.write( "B-9[B-32+8B]=608 \n" ); document.write( "Combining like-terms inside brackets: \n" ); document.write( "B-9[9B-32]=608 \n" ); document.write( "Distribute the -9 to terms inside brackets: \n" ); document.write( "B-81B+288=608 \n" ); document.write( "Combining like-terms: \n" ); document.write( "-80B+288=608 \n" ); document.write( "Subtracting 288 from both sides \n" ); document.write( "-80B=608-288 \n" ); document.write( "-80B=320 \n" ); document.write( "Dividing both sides by -80 \n" ); document.write( "B = -4\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
