Question

Find the solution to this equation.

x + 4 = 2x + 8
2
A
All real numbers
B.
No solution

Answer 1

A. All real numbers.

Explanation:

`x + 4 = (2x + 8)/(2) \: \: multipling \: both \: sides \: by \: 2 \\ 2(x + 4) = 2x + 8 \\ 2x + 8 = 2x + 8`

When you end up with a true statement like this, it means that the solution to the equation is “all real numbers”. Any value for x that you can think of will make this equation true.

Answer 2

No solution, the result of doing the problem is x-4=x which is impossible
