The first statement assigns the number -3 to the variable x. So wherever you see an x, just replace it with -3. This is for a temporary time.
In line 2, it states "repeat the following block of code until x = 7 or larger" (paraphrased). The "block" being anything in the curly braces. In this case, we only have one command in the braces. That command being "whatever x is, add on 3 and assign it to x". So we add 3 to the previous value of x.
If we started with x = -3, then we'll jump to x = 0 after adding on 3. Then we'll get to x = 3 and x = 6, etc.
The list of x values we'll work with is: -3, 0, 3, 6, 9
Once we reach 9 is when the condition [tex]x \ge 7[/tex] is met, ie is true. At this point, the block of code is not executed anymore and we leave that block.
The last line of code is to print out or display the value of x. It should display 9. Keep in mind that the other x values are not displayed. Only that final x value is shown.
Final Answer: 9
