if -9x = 45

we need to get only one x, so we need to devide by 9 to get one x. But what we do to the left hand side we must do to the right hand side to keep the equation balanced, so we must also devide the right hand side by 9 to give:

-x = 5

now to get a positive x we need to multiply the x by -1 (minus times minus=plus), and remember what we do to the left hand side we must do to the right hand side to keep the equation balanced. This gives:

x = -5
