一個(gè)有理數(shù)在數(shù)軸上對(duì)應(yīng)的點(diǎn)為A,將A點(diǎn)向左移動(dòng)3個(gè)單位長(zhǎng)度再向左移動(dòng)2個(gè)單位長(zhǎng)度,
得到點(diǎn)B,點(diǎn)B所對(duì)應(yīng)的數(shù)和點(diǎn)A的絕對(duì)值相等,求點(diǎn)A對(duì)應(yīng)的數(shù)到點(diǎn)B,點(diǎn)B所對(duì)應(yīng)的數(shù)和點(diǎn)A的絕對(duì)值相等,求點(diǎn)A對(duì)應(yīng)的數(shù)點(diǎn)B所對(duì)應(yīng)的數(shù)和點(diǎn)A的絕對(duì)值相等,求點(diǎn)A對(duì)應(yīng)的數(shù)
求點(diǎn)A對(duì)應(yīng)的數(shù)點(diǎn)B所對(duì)應(yīng)的數(shù)和點(diǎn)A的絕對(duì)值相等，
