Answer 2

To solve the equation $\frac{2x + 1}{1.3} = \frac{2.5}{0.65}$ for $x$, follow these steps:

Step 1: Cross-multiply to eliminate fractions.

$(2x + 1) \cdot 0.65 = 2.5 \cdot 1.3$

Step 2: Distribute on the left side and calculate on both sides.

$1.3x + 0.65 = 3.25$

Step 3: Subtract 0.65 from both sides to isolate $x$.

$1.3x = 2.6$

Step 4: Divide by 1.3 to solve for $x$.

$x = \frac{2.6}{1.3} = 2$

So, the solution to the equation is $x = 2$.
