9 – nx = 17nx solve for x Explain how to do it

Hi :)

x = 1/2n

Subtract 17nx from both sides
9−nx−17nx = 0

Combine −nx and −17nx to get −18nx
9 −18nx = 0

Subtract 9 from both sides
−18nx = −9

The equation is in standard form
(−18n)x=−9

Divide both sides by −18n
(-18n)x/ -18n = -9/ -18n


Dividing by −18n undoes the multiplication by −18n
x= -9/ -18n


Divide −9 by −18n
x= 1/2n

Hope this helps :)
