2x+6 chia hết cho x+1

=>2(x+1)+4 chia hết cho x + 1

=> 4 chia hết cho x + 1

=> x+1 thuộc Ư(4)={±1;±2;±4}

=> x thuộc {0;-2;1;-3;3;-5}

Mỗi giờ làm chung, hai bạn làm được:

1:7= 1/7 (công việc)

Lượng việc Tâm phải làm 1 mình là:

1 - 5 x 1/7 = 2/7 (công việc)

Mỗi giờ Tâm làm 1 mình được:

2/7 : 6= 1/21 (công việc)

Nếu làm 1 mình, để hoàn thành công việc Tâm mất:

1 : 1/21= 21(giờ)

1 giờ làm 1 mình thì Thành làm được:

1/7 - 1/21= 2/21(công việc)

Nếu làm 1 mình, để hoàn thành công việc Thành mất:

1: 2/21= 10,5(giờ)
