Question

3x – 7 –2/3 (9x – 6) = 15

with explanation.

Answer 1

Solution.

We need to find the value of x for the given expression.

`(3x-7-2)/(3(9x-6))=15`

or

`(3x-9)/(3(9x-6))=15`

Firstly, cross multiplying both sides,

`3x-9=45(9x-6)`

or

`3x-9=405x-270`

Taking like terms together,

`3x-405x=-270+9\\\\-402x=-261\\\\x=(261)/(402)\\\\x=(87)/(134)`

So, the value of x is
`(87)/(134)`
