Explanation:

Step1: Add 3.67 to both sides

To isolate the term with \( x \), we add 3.67 to both sides of the equation \( 2.5x - 3.67 = 1.52 \). This gives us \( 2.5x - 3.67 + 3.67 = 1.52 + 3.67 \), which simplifies to \( 2.5x = 5.19 \).

Step2: Divide by 2.5

Now, to solve for \( x \), we divide both sides of the equation \( 2.5x = 5.19 \) by 2.5. So, \( x=\frac{5.19}{2.5} \), and calculating this gives \( x = 2.076 \).

Answer:

\( x = 2.076 \)
