Final answer:

Yes, the solution to the equation -x + 4 = 2x - 8 is (4, 0).


Step-by-step explanation:

Yes, your friend is correct. The solution of the equation -x + 4 = 2x - 8 is indeed (4, 0). To find the solution, we can solve the equation by setting -x + 4 equal to 2x - 8 and then solving for x.

-x + 4 = 2x - 8

Combine like terms: -x - 2x = -8 - 4

-3x = -12

Divide by -3: x = 4

Plugging this value of x back into either equation, we find that y = 0.

Therefore, the solution to the equation is (4, 0) which is the point of intersection of the two lines.
