x-100+13•2=223

To solve the equation \( x - 100 + 13 \cdot 2 = 223 \), follow these steps:

1. Calculate \( 13 \cdot 2 \): \[ 13 \cdot 2 = 26 \]

2. Substitute this value back into the equation: \[ x - 100 + 26 = 223 \]

3. Simplify the equation: \[ x - 74 = 223 \]

4. Add 74 to both sides to isolate \( x \): \[ x = 223 + 74 \] \[ x = 297 \]

So, the solution is \( x = 297 \).
