Problem maths

x/7 + 2π - 6.3068 = 0
x/7 = - (2π - 6.3068)
x = 7(6.3068 - 2π)
x = 0.165

Now, I'm quite confused because I thought it was supposed to go like this:
x/7 + 2π - 6.3068 = 0
x/7 = -2π + 6.3068
x = -2π + 6.3068 x 7

Can someone tell me why my approach is incorrect?

you forgot to multiply the $2 \pi$ by 7 too
