Question

If 8a+2b+6c=−6 what is 16a+4b+12c

Answer 1

16a+4b+12c=2(8a+2b+6c)=-6*2=-12

Answer 2

`16a+4b+12c=-12`

Explanation:

Given : If
`8a+2b+6c=-6`

To find : What is
`16a+4b+12c` ?

Solution :

We have given the expression,

`8a+2b+6c=-6`

To get the expression
`16a+4b+12c`

We have seen that each term is multiple of 2 of the expression
`8a+2b+6c`

So, Multiplying the given expression by 2 both side,

`2(8a+2b+6c)=-6(2)`

`16a+4b+12c=-12`

Therefore, The value is
`16a+4b+12c=-12`
