A+B = 88 subtract A from both sides: B = 88-A \n" ); document.write( "A-8 = 3(B-8) \n" ); document.write( "A-8 = 3B-24 Substitute for B: \n" ); document.write( "A-8 = 3(88-A)-24 \n" ); document.write( "A-8 = 264-3A-24 \n" ); document.write( "A-8 = 240-3A Add 3A and 8 on both sides: \n" ); document.write( "4A = 248 Divide both sides by 4: \n" ); document.write( "A = 62 \n" ); document.write( " \n" ); document.write( " |
