See a solution process below:

Explanation:

First, subtract #color(red)(20)# from each side of the equation to isolate the #x# term while keeping the equation balanced:

#-5x + 20 - color(red)(20) = 10 - color(red)(20)#

#-5x + 0 = -10#

#-5x = -10#

Next, divide each side of the equation by #color(red)(-5)# to solve for #x# while keeping the equation balanced:

#(-5x)/color(red)(-5) = (-10)/color(red)(-5)#

#(color(red)(cancel(color(black)(-5)))x)/cancel(color(red)(-5)) = 2#

#x = 2#

Given,

#-5x +20=10#

or, #-5x = 10-20#

or, #-5x = -10#

or, #x=(-10)/(-5) =2#

#x=2#

Explanation:

To isolate the #x# term, we can start by subtracting #20# from both sides to get

#-5x=-10#

Lastly, we would divide both sides by #-5# to get

#x=2#

Hope this helps!
