Answer:

13 is your answer

Step-by-step explanation:

x - 8.1 = 5.3

  +8.1    +8.1         Add 8.1 to both sides

x     =     13.4

Which if you want the whole number i'd be 13, Because if your rounding the 3, 4 won't bump the 3 up any because 4 isn't greater than 5.

Hope my answer has helped you!

Answer:

x=13

Step-by-step explanation:

A quick rough estimate could be obtained by adding 8 to both sides:

x = 5.3 + 8, or x = 13 (approx.)

The exact solution is x = 8.1 + 5.3 = 13.4 (which rounds down to 13).
