Question 76266
This is pretty simple. We just need to isloate x on one side of the equation, by applying the same operation on both sides (pretty much the way you solve equations with only one letter).

{{{cartoon(y = 5x - 5,
y + highlight(5) = 5x - 5 + highlight(5),
y + 5 = 5x - cross(5) + cross(5),
y + 5 = 5x,
(y+5)/highlight(5) = 5x/highlight(5),
(y+5)/5 = cross(5)x/cross(5),
(y+5)/5 = x
)}}}

which can also be written as

{{{y/5 + 1 = x}}}
