Hello from MrBillDoesMath!

Answer:

Yes!


Discussion:

a + b= 2a                =>  subtract "a" from both sides

a - a + b = 2a - a    =>  as (a-a) = 0 and (2a-a) = a

b = a                      (*)

Then  from (*) above

      b-a = b - b       => b-b = 0

      b -a = 0



Thank you,

MrB

A and B working together can do a work in 6 days. If A takes 5 days less than B to finish the work, in how many days B alone can
svetlana [45]

Answer:

15 days

Step-by-step explanation:

Let x be the number of days needed for B to complete the job. Then x-5 is the number of days needed for A to complete the job.

In 1 day,

  • A completes \dfrac{1}{x-5} of all work;
  • B completes \dfrac{1}{x} of all work.

Hence, in 1 day both A and B complete \dfrac{1}{x-5}+\dfrac{1}{x} of all work. A and B working together can do a work in 6 days. Then

6\cdot \left(\dfrac{1}{x-5}+\dfrac{1}{x}\right)=1.

Solve this equation:

\dfrac{6x+6x-30}{x(x-5)}=1,\\ \\12x-30=x^2-5x,\\ \\x^2-17x+30=0,\\ \\D=(-17)^2-4\cdot 30=289-120=169=13^2,\\ \\x_{1,2}=\dfrac{17\pm 13}{2}=2,\ 15.

If x=2, then x-5=-3 that is impossible. So, B needs 15 days to complete the work alone.
