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