Question

-6x + 9= 25 what is the number for x and how do you get it?

Answer 1

The aim is to isolate x on one side of the equation

-6x + 9 = 25

Subtract 9 from each side:-

-6x + 9 - 9 = 25 - 9

-6x + 0 = 16

Now divide both sides by -6:-

x = 16 / -6

x = -2 2/3   (answer)

Answer 2

x = - $\frac{8}{3}$

isolate - 6x by subtracting 9 from both sides

- 6x = 16 ( divide both sides by - 6 )

x = $\frac{16}{-6}$ = - $\frac{8}{3}$
