Solve the equation.

4x + 2 = 5(x + 10)

4x + 2 = 5(x + 10)

4x + 2 = 5x + 50

- x = 48

x = -48

How does the positive 48 become a negative 48?

Because - x = 48 so the inverse is true.

I could have done the problem this way.

4x + 2 = 5(x + 10)

4x + 2 = 5x + 50

2 - 50 = x

-48 = x

To solve the equation 4x + 2 = 5(x + 10), follow these steps:

Step 1: Distribute the 5 on the right side of the equation:
4x + 2 = 5x + 50

Step 2: Move all the x terms to one side of the equation by subtracting 4x from both sides:
4x - 4x + 2 = 5x - 4x + 50
2 = x + 50

Step 3: Move the constant term (50) to the other side of the equation by subtracting 50 from both sides:
2 - 50 = x + 50 - 50
-48 = x

Therefore, the solution to the equation 4x + 2 = 5(x + 10) is x = -48.
