Question

-4x+7x=4(x+2)-(x+8)

Answer 1

The best way to figure out if there is a solution to the equation:

--> solve this whole thing algebraically

Let's solve:

`-4x+7x=4(x+2)-(x+8)\\3x=4x+8-x-8\\3x=3x`

If we get this kind of circumstance:

--> where the left/right part of the equation are equal and cannot be

solved further

---> the solution is all real numbers

Answer: solution is all real numbers
