#x = -3/4#

Here's how I did it:

#5-8x = 11#

In equations, we know that one side equals the other, so anything we do on one side of the equation must also be done on the other side.

Keeping this in mind, we can subtract #5# from both sides of the equation:

#5quadcolor(red)(-quad5) - 8x = 11quadcolor(red)(-quad5)#

#-8x = 6#

Now we divide both sides by #-8#:
#x = -6/8#

We can still simplify this to:
#x = -3/4#
because #(-6/8 -:2/2 = -3/4)#

Hope this helps!
