18/u = 3

1/u =1/6

u= 6

hope it helped

Answer 2

Solution:

${\frac{18}{u}}+5=8$

Multiply all terms by u and cancel:

$⟹18+5u=8u$

$⟹18=8u-5u$

$⟹18=3u$

$⟹u=$${\frac{18}{3}}$

$⟹u=6$

Verification:

${\frac{18}{u}}+5=8$

$⟹{\frac{18}{6}}+5=8$

$⟹3+5=8$

$⟹8=8$

$⟹L.H.S=R.H.S$

Thus, verified.

Value of u = 6
