-9x + x = 17 - 1

-8x = 16

Divide both sides of the equation by -8 to get x

x = -2

Hope this helps!

Add an x to get rid of the -x on the right-hand side

-9x + 1 + x = 17

Tidy

-8x +1 = 17

Take away 1 from both sides to get rid of the 1 on the left-hand side

-8x = 17 -1 

Tidy

-8x - 16

Solve by dividing by -8 to get x on its own

x = 16/-8 = -2
