7,8+x/2=7,2

Let's clarify and solve the equation:

Given: \(7,8 + \frac{x}{2} = 7,2\)

Note: It looks like a comma is used as the decimal separator, common in some countries. So:

• \(7,8\) = 7.8
• \(7,2\) = 7.2

Rewriting the equation:

\[7.8 + \frac{x}{2} = 7.2\]

Step 1: Subtract 7.8 from both sides:

\[ \frac{x}{2} = 7.2 - 7.8 = -0.6 \]

Step 2: Multiply both sides by 2 to solve for \(x\):

\[ x = -0.6 \times 2 = -1.2 \]

Final answer:

\[ \boxed{x = -1.2} \]
