Question

Which value for x satisfies the given equation 1/3(6x+9)=12

Answer 1

`x=(27)/(6)`

Explanation:

So I'm going to assume you mean to write:
`(1)/(3)(6x+9)=12`

In this equation here we want to cancel out the "1/3", and this can be done by multiplying both sides by "3", since we can multiply the 1/3 by 3 on the left side and that just gives us 3/3 or 1, which doesn't change the value

We have to do this on both sides to remain equality and this gives us the equation

`6x+9=36`

Now from here just subtract 9 from both sides to cancel out the +9

`6x=27\\x=(27)/(6)`
