Answer:
To solve the equation -17 = 2x + 9, we want to isolate the variable x. Let's go step by step:
Step 1: First, we want to get rid of the 9 on the right side of the equation. We can do this by subtracting 9 from both sides:
-17 - 9 = 2x + 9 - 9
-26 = 2x
Step 2: Now we need to isolate the variable x. Since 2x means 2 times x, we need to undo that by dividing both sides of the equation by 2:
-26 ÷ 2 = 2x ÷ 2
-13 = x
So, the solution to the equation -17 = 2x + 9 is x = -13.
