Answer 2

Solving the Equations

Let's solve the given equations step by step:

1) Equation: 2x + 1/1.3 = 2.5/0.65

To solve this equation, we can start by simplifying both sides. On the left side, we can multiply 1/1.3 by 10/10 to get a common denominator:

2x + 10/13 = 2.5/0.65

Next, we can convert the fractions on the right side to decimals:

2x + 10/13 = 3.846/0.65

Now, we can multiply both sides by 0.65 to eliminate the fraction on the right side:

0.65 * (2x + 10/13) = 0.65 * (3.846/0.65
