Question

I don't know how to fan or sub but please help It would be very appreciated!
Which of the following best describes the equation below?
2(x + 12) + 7x = 9x - 24
A. infinite real solutions,
B. exactly one real solution, x = 6.85,
C. exactly one real solution, x = -1,
or D. no real solutions
no real solutions

Answer 1

distribute, collect like terms, and then isolate the x

Answer 2

if there are no x parts left in the end, then you can simply see if the final results are true or false.

if the setup doesnt depend on the value of x, then it is either true for all x values, or false for all x values.

Answer 3

thank you
