Basically you want to make the equation so that you have
x>something or x<something so basically solve for x or isolate x so
a+bx>cx-d
try to get all the x's on one side
subtract bx from both sides
a>cx-bx-d
add d to both sides
a+d>cx-bx
undistribute
a+d>(x)(c-b)
divide both sides by (c-b)
tada
so the solution is
>x or
x<
x>something or x<something so basically solve for x or isolate x so
a+bx>cx-d
