Answer 2

Let's solve the given equations step by step:

1. 2x - 5/3 = 2x + 1/5

To solve this equation, we want to isolate the variable x on one side of the equation. Here's how to do it:

Step 1: Get rid of the fractions by finding a common denominator, which is 15 in this case.

Multiply the entire equation by 15 to eliminate the fractions:

15 * (2x - 5/3) = 15 * (2x + 1/5)

Step 2: Distribute the multiplication:

30x - 25 = 6x + 3

Step 3: Move all the x terms to one side and the constant terms to the other side:

30x - 6x = 3 + 25

Step 4: Combine like terms:

24x = 28

Step 5: Solve for x:

x = 28 / 24

Simplify the fraction:

x = 7 / 6

So the solution for the equation is x = 7/6.

2. 4.3 - 0.5(x - 4) = 2(9 - 0.3x)

Step 1: Distribute the multiplication on the right side:

4.3 - 0.5x + 2 = 18 - 0.6x

Step 2: Combine like terms:

6.3 - 0.5x = 18 - 0.6x

Step 3: Move all the x terms to one side and the constant terms to the other side:

-0.5x + 0.6x = 18 - 6.3

Step 4: Combine like terms:

0.1x = 11.7

Step 5: Solve for x:

x = 11.7 / 0.1

x = 117

So the solution for the equation is x = 117.
