Question

Solve for u .

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

Simplify your answer as much as possible.

Answer 1

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 =
`\frac {- 54}{- 6}` =
`\frac {54}{6}` = 9

Hence,
The required answer is 9

Answer 2

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


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


`- 4u + 38 = 2u - 16`
Subtract 2u from both sides.


`- 6u + 38 = - 16`
Subtract 38 from both sides.


`- 6u = - 54`
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.


`u = ( - 54)/( - 6) = 9`
Hence, the answer is u = 9.
