133+x+57=218

To solve the equation \( 133 + x + 57 = 218 \), you can follow these steps:

1. Combine the constant terms on the left side: \[ 133 + 57 = 190 \] So the equation simplifies to: \[ 190 + x = 218 \]

2. Next, isolate \( x \) by subtracting 190 from both sides: \[ x = 218 - 190 \] \[ x = 28 \]

Therefore, the solution is \( x = 28 \).
