Estimate the solution of the equation x – 8.1 = 5.3 to the nearest whole number.

Answer 1

To estimate the solution of the equation x - 8.1 = 5.3 to the nearest whole number, we can add 8.1 to both sides of the equation to isolate x:

x - 8.1 + 8.1 = 5.3 + 8.1

This simplifies to:

x = 13.4

To the nearest whole number, the solution of the equation is 13.
