Answer 2

Solving the Equation with Decimals, Fractions, and Mixed Numbers

To solve the equation 7/8x + 0.2 = 2 + 1/5x + 0.8/20, we can follow these steps:

1. Combine like terms on both sides of the equation. 2. Isolate the variable term on one side of the equation. 3. Solve for the variable.

Let's start by solving the equation step by step.

Step 1: Combine Like Terms

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

On the left side: - 7/8x and 1/5x are the variable terms. - 0.2 is the constant term.

On the right side: - 2 is the constant term. - 0.8/20 can be simplified to 0.04.

So, the equation becomes: 7/8x - 1/5x = 2 - 0.2 - 0.04

Step 2: Combine Variable Terms

Now, let's combine the variable terms on the left side of the equation.

7/8x - 1/5x can be simplified to (7/8 - 1/5)x.

Step 3: Isolate the Variable Term

Next, let's isolate the variable term on one side of the equation.

7/8 - 1/5 can be calculated to find the combined coefficient of x.

Step 4: Solve for the Variable

After combining the coefficients, we can solve for x.

Let's calculate the combined coefficient of x and solve for the variable.

I'll now calculate the combined coefficient and solve for x.
