(850+×):18+(19•700):700

To solve the expression \((850 + x):18 + (19 \cdot 700):700\), let's break it down into parts.

1. First, simplify \((19 \cdot 700):700\): \[ (19 \cdot 700) : 700 = 19 \]

2. Now, rewrite the original expression with this simplification: \[ (850 + x):18 + 19 \]

3. Next, we need to simplify \((850 + x):18\): \[ (850 + x):18 = \frac{850 + x}{18} \]

4. Now our expression is: \[ \frac{850 + x}{18} + 19 \]

5. If you want a single expression, you can add 19 to the fraction: \[ \frac{850 + x}{18} + 19 = \frac{850 + x + 19 \cdot 18}{18} \]

6. Calculate \(19 \cdot 18\): \[ 19 \cdot 18 = 342 \]

7. Now substitute back into the expression: \[ \frac{850 + x + 342}{18} = \frac{1192 + x}{18} \]

Thus, the final result is: \[ \frac{1192 + x}{18} \]
