Algebra.Com's Answer #666985 by addingup(3677)![]() ![]() You can put this solution on YOUR website! A = 3B divide both sides by 3: B = 1/3A \n" ); document.write( "A = C+16 Subtract 16 on both sides: C = A-16 \n" ); document.write( ": \n" ); document.write( "A+1/3A+A-16 = 180 \n" ); document.write( "A+1/3A+A = 196 \n" ); document.write( "3/3A+1/3A+3/3A = 196 \n" ); document.write( "7/3A = 196 multiply both sides times 3 \n" ); document.write( "7A = 588 \n" ); document.write( "A = 84 \n" ); document.write( "B = 84/3 = 28 \n" ); document.write( "C = 84-16 = 68 \n" ); document.write( "------------------- \n" ); document.write( "Check: \n" ); document.write( "84+28+68 = 180 Correct \n" ); document.write( ": \n" ); document.write( "John \n" ); document.write( " |
