Question

Twice the sum of a number and six is eight

Answer 1

This can be represented as:

`2(x + 6) = 8`
Open the bracket:

`2x + 12 = 8`
Collect like terms:

`2x = 8 - 12`
Simplify :

`2x = - 4`
Divide both sides by 2:

`x = - 2`
You can check the answer by inputting - 2 in the first equation:

`2( - 2 + 6) = 8`

`2(4) = 8`

`8 = 8`
