a/3+1+(2a+1)/3=0
a/3+1+2/3a+1/3=0
a/3+2/3a=-1-1/3
a=-4/3
選C方程4x-1.5/0.5=1-x-1.1/0.1將小數(shù)化為整數(shù)變形得40x-15/( )=1-( )/1.(4x-1.5)/0.5=1-x-1.1/0.1將小數(shù)化為整數(shù)變形得（40x-15）/( 5)=1-(11 )/1.你要注意加括號，否則答案不一樣
若a/3+1與2a+1/3互為相反數(shù),則a的值為( ) A.4/3 B.10 C.-4/3 D.-10
若a/3+1與2a+1/3互為相反數(shù),則a的值為( ) A.4/3 B.10 C.-4/3 D.-10
