To solve the equation, we will first simplify both sides:
9(x + 1) = 3(5x + 1) - 12
Expanding both sides:
9x + 9 = 15x + 3 - 12
Combining like terms:
9x + 9 = 15x - 9
Now, let's isolate the x term on one side:
9x - 15x = -9 - 9
-6x = -18
Dividing both sides by -6:
x = 3
So, the equation has one solution: x = 3.
Therefore, the correct answer is:
A. The equation has one solution: x = 3
Solve for x
to determine if the equation has one, none, or infinite solutions.
9(x+1)=3(5x+1)−12
