Solve for x : 4x−3=3x−9

1 answer

To solve for x in the equation 4x - 3 = 3x - 9, we need to isolate the variable x by moving all terms without x to one side of the equation.

First, let's move the 3x term to the left side of the equation by subtracting 3x from both sides:

4x - 3 - 3x = 3x - 3x - 9
x - 3 = -9

Now, let's isolate x by adding 3 to both sides:

x - 3 + 3 = -9 + 3
x = -6

Therefore, the solution to the equation is x = -6.
