Answer 2

Solving the Equation

To solve the equation x + 4/7 = 3x + 2/5, we can follow these steps:

1. Isolate the variable x on one side of the equation: - Subtract 3x from both sides of the equation to move all terms containing x to one side.

2. Combine like terms: - Combine the constants on the other side of the equation.

3. Solve for x: - Once x is isolated, solve for its value.

Following these steps, the solution to the equation is as follows:

Step 1: Isolate the variable x - x + 4/7 = 3x + 2/5 - x - 3x = 2/5 - 4/7 - -2x = (2*7 - 4*5) / (5*7) - -2x = (14 - 20) / 35 - -2x = -6 / 35

Step 2: Combine like terms - -2x = -6 / 35 - x = (-6 / 35) / -2 - x = 6 / (35*2) - x = 6 / 70 - x = 3 / 35

Step 3: Solve for x - Therefore, the solution to the equation x + 4/7 = 3x + 2/5 is x = 3/35.

The solution to the equation is x = 3/35.
