How many solutions for x does the following equation have?
3(X + 8) - 1 = 3x + 4
A. 4
B. O
c.1
D. infinite

Respuesta :

Answer:

B. No solutions.

Step-by-step explanation:

Let's try solving it:

3(x + 8) = 3x + 4

3x + 8 = 3x + 4.

There are no solutions  because if we simplify we get an absurd result. Subtract 3x from both sides of the equation:

3x - 3x + 8 = 3x - 3x + 4

8 = 4.
