$\\ \sf\longmapsto -4d-5=-1$

Cancel - from both sides

$\\ \sf\longmapsto -(4d+5)=-(1)$

$\\ \sf\longmapsto 4d+5=1$

$\\ \sf\longmapsto 4d=1-5$

$\\ \sf\longmapsto 4d=-4$

$\\ \sf\longmapsto d=\dfrac{-4}{4}$

$\\ \sf\longmapsto d=-1$

sally can paint a room in 7 hours while it taks steve 9hours to finsh the same room. how ling will it take them to paint if they

Nata [24]

How much part can sally paint in an hour ?
a ÷ 7 = a/7

And what about Steve ?
a ÷ 9 = a/9

Where, a is the total area of the room.

So, let the time taken by both of them to paint the room together be 't'

So,
t(a/7 + a/9) = a
t(9a/63 + 7a/63) = a
t(16a/63) = a
t = 63/16 ≈ 4 hr
