To solve for x, we can simplify the equation first:
9(x+1) = 3(5x+1) - 12
Expanding the brackets, we get:
9x + 9 = 15x + 3 - 12
Combine like terms:
9x + 9 = 15x - 9
Subtract 9x from both sides:
9 = 6x - 9
Add 9 to both sides:
18 = 6x
Divide both sides by 6:
3 = x
Therefore, 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
