xx = -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
