Hi there!
Let's solve this equation step by step!

[tex] - 4u + 38 = 2(u - 8)[/tex]
First work out the parenthesis, which can for instance be done using rainbow technique.

[tex] - 4u + 38 = 2u - 16[/tex]
Subtract 2u from both sides.

[tex] - 6u + 38 = - 16[/tex]
Subtract 38 from both sides.

[tex] - 6u = - 54[/tex]
And finally divide both sides by -6, in order to isolate the variable u. Remember that dividing a negative by a negative gives a positive outcome.

[tex]u = \frac{ - 54}{ - 6} = 9[/tex]
Hence, the answer is u = 9.

Hi there!

Simplify th' Eqⁿ :-

- 4u + 38 = 2(u - 8)

- 4u + 38 = 2(u) - 2(8)

- 4u + 38 = 2u - 16

Combine like terms together :-

- 4u - 2u = - 38 - 16

- 6u = - 54

u = [tex]\dfrac {- 54}{- 6}[/tex] = [tex]\dfrac {54}{6}[/tex] = 9

Hence,
The required answer is 9

~ Hope it helps!
