4x - 20 = -28 + 5x

1 answer

To solve for x in the equation 4x - 20 = -28 + 5x, we can start by getting all the x terms on one side of the equation.

First, we can subtract 4x from both sides to eliminate the variable from the left side:

4x - 4x - 20 = -28 + 5x - 4x

This simplifies to:

-20 = -28 + x

Next, we can add 28 to both sides to get rid of the constant term on the right side:

-20 + 28 = -28 + x + 28

This simplifies to:

8 = x + 0

Or:

8 = x

So the solution to the equation is x = 8.
