Answer :
To solve for x in the equation +8=9, you need to isolate x on one side of the equation. Here's how you can do it step by step:
1. Start with the equation +8=9.
2. Subtract 8 from both sides of the equation to isolate x. This gives you:
+8 - 8 = 9 - 8
This simplifies to:
x = 1
Therefore, the solution for x in the equation +8=9 is x = 1.
