-4=x/20-5 Solve for x

x = 20

Step-by-step explanation:

I'm no mathematician but...

- 4 = x / 20 - 5

If you move the five to the other side using addition you get:

1 = x / 20

Then multiply 20 on both sides

20 = x

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph
