х+320=80*7

To solve this equation, we can start by simplifying the right side of the equation:

80 * 7 = 560

Now, we have the equation:

х + 320 = 560

To isolate the variable "x", we can subtract 320 from both sides of the equation:

х + 320 - 320 = 560 - 320

This simplifies to:

х = 240

So the solution to the equation is x = 240.
