Answer 2

Solving the Equation 8.6x - 1.9x - 1.3 = 15.9 + 2.4x

To solve the equation 8.6x - 1.9x - 1.3 = 15.9 + 2.4x, we can follow these steps:

1. Combine like terms on both sides of the equation. 2. Move the variable terms to one side and the constant terms to the other side. 3. Solve for the variable x.

Step 1: Combine Like Terms

First, let's combine the like terms on both sides of the equation:

8.6x - 1.9x - 2.4x = 15.9 + 1.3

Step 2: Simplify the Equation

Now, simplify the equation by combining the x terms and the constant terms:

(8.6 - 1.9 - 2.4)x = 15.9 + 1.3 4.3x = 17.2

Step 3: Solve for x

To solve for x, divide both sides by 4.3:

x = 17.2 / 4.3 x = 4

So, the solution to the equation 8.6x - 1.9x - 1.3 = 15.9 + 2.4x is x = 4.
