Question #b68bf

Answer 1

`x` = -2.8

Explanation:

Start by taking the `x's` on one side and numbers on the other side. (remember to change + or - signs when transferring one number or letter to opposite sides).

-5 -9 = `7x-2x`

Now, simplify the equation.

-14 = `5x`

Now, make `x` the subject of the formula.

`-14/5` = `x`

Work out the value using a calculator.

`:.` -2.8 = `x`
