Question

4 men or 6 women can finish a piece of work in 20 days. In how many days can 6 men and 11 women finish the same work?​

Answer 1

Answer:

let 4men be = x

and let 6women = y

so 4 x +6 y =20

6 x + 11 y =

lets eliminate x  4x +6y=20

                           6x+11y=

    lets multi both side by 4 and 6

24x+36y=120

24x+44y=

0 -8y =120

y=120/-8

y=-15

4x+(-15)=20

4x=-300

x=-300/4

-75
