9(x+1)=3(5x+1)-12
Distributing on both sides of the equation:
9x + 9 = 15x + 3 - 12
Combining like terms:
9x + 9 = 15x - 9
Subtracting 15x from both sides:
-6x + 9 = - 9
Subtracting 9 from both sides:
-6x = -18
Dividing both sides by -6:
x = 3
Therefore, the solution to the equation is x = 3. Therefore, the equation has one solution.
Solve for x
to determine if the equation has one, none, or infinite solutions.
