9x + 12 = 3x -6 how many solutions are there for this problem

1 answer

To find the number of solutions for this equation, let's solve it:

9x + 12 = 3x - 6

First, let's simplify the equation by combining like terms:

9x - 3x + 12 = -6

6x + 12 = -6

Next, let's isolate the variable by subtracting 12 from both sides:

6x = -18

Finally, let's solve for x by dividing both sides by 6:

x = -18/6

Simplifying, we have:

x = -3

Therefore, the equation has only one solution, which is x = -3.
