Question

How do you solve `0.5(2x - 4) = -17`?

Answer 1

`x=-15`

Explanation:

`"distribute the bracket"`

`x-2=-17`

`"add 2 to both sides"`

`xcancel(-2)cancel(+2)=-17+2`

`x=-15`

`color(blue)"As a check"`

Substitute this value into the left side of the equation and if equal to the right side then it is the solution.

`0.5(-30-4)=0.5xx-34=-17`

`x=-15" is the solution"`

Answer 2

`x=-15`

Explanation:

`0.5(2x-4)=-17`

Double both sides

`2x-4=-34`

Add 4 to both sides

`2x=-30`

Divide both sides by 2

`x=-15`
