Answer:
Step-by-step explanation:
Unfortunately, your " 12×+9=10×1 " can be interpreted in more than one way. The symbol " × " should be used ONLY to indicate multiplication. Thus, " 12× " reads as ' 12x.' Then we have: 12x + 9 = 10. Unsure of what you meant by " 10×1". So I will treat your "10×1" as simply '10.'
Then we have 12x + 9 = 10, which reduces to 12x = 1 if we subtract 9 from both sides.
12x = 1 yields x = 1/12.
If this is not the result you expected, please go back to the original problem and share it as accurately as you can.
