Question

6u+18+9u=-12 simplify

Answer 1

U= -2 I think that’s the answer

Answer 2

u = -2

Explanation:

Group

`6u+9u+18=-12`

Add similar elements in the equation

`15u+18=-12`

Subtract 18 from all sides

`15u+18-18=-12-18`

Simplify this

`15u=-30`

Divide all sides by 15

`(15u)/(15)=(-30)/(15)`

Divide 15 by 15, removing u

`(15)/(15) = u`

Transform
`(-30)/(15)` by using the fraction rule.

`-(30)/(15)`

Divide 30 by 15.

`(30)/(15) = 2`

Thus,

u = -2
