Solving the Equation: (x-10) + (4x-10) = 90

This article will guide you through the steps to solve the equation (x-10) + (4x-10) = 90.

First, we need to combine like terms on the left side of the equation.

Now the equation is: 5x - 20 = 90

To get 'x' by itself, we need to get rid of the '-20'. We can do this by adding 20 to both sides of the equation.

Finally, we need to isolate 'x' by dividing both sides of the equation by 5.

Therefore, the solution to the equation (x-10) + (4x-10) = 90 is x = 22.

We can verify our solution by plugging 'x = 22' back into the original equation.

This confirms that our solution is correct.
