324+x=851-263

To solve the equation \( 324 + x = 851 - 263 \), first simplify the right side:

1. Calculate \( 851 - 263 \): \[ 851 - 263 = 588 \]

Now the equation becomes: \[ 324 + x = 588 \]

Next, isolate \( x \) by subtracting 324 from both sides: \[ x = 588 - 324 \]

Now calculate \( 588 - 324 \): \[ 588 - 324 = 264 \]

So, the value of \( x \) is: \[ x = 264 \]
