9x+13=3(3x+4)

a. 13=13;infinite real solutions
b. x=12;exactly one real solution
c. x=13;exactly one real solution
d. no real solutions

1 answer

To find the value of x, we can distribute the 3 on the right side of the equation:

9x + 13 = 9x + 12

Next, we can subtract 9x from both sides to isolate the constant term:

13 = 12

This is not a true statement, meaning there are no real solutions to the equation.

Therefore, the answer is d. no real solutions.
