solve for x: 4x - 3 = 3x - 9
To solve for x, we need to isolate the variable on one side of the equation.
4x - 3 = 3x - 9
First, let's subtract 3x from both sides:
4x - 3 - 3x = 3x - 9 - 3x
After simplifying, this becomes:
x - 3 = -9
Next, we add 3 to both sides:
x - 3 + 3 = -9 + 3
After simplifying, this becomes:
x = -6
So the solution is x = -6.
