Answer:
x = 8
Step-by-step explanation:
x + 2 = 10
x = 10 - 2
x = 8
8 + 2 = 10
You want to combine both equations so it would be the first option.
If you would like to convert 534.3% to a decimal, you can do this using the following steps:
534.3% = 534.3 / 100 = 5.343
The correct result would be 5.343.
