4x-189=578

To solve the equation, we can isolate the variable by performing the necessary operations to both sides of the equation.

Starting with the given equation: 4x - 189 = 578

First, let's isolate the variable term, 4x, by adding 189 to both sides:

4x - 189 + 189 = 578 + 189

This simplifies to:

4x = 767

Next, to solve for x, divide both sides of the equation by 4:

4x/4 = 767/4

This further simplifies to:

x = 191.75

Therefore, the solution to the equation 4x - 189 = 578 is x = 191.75.
