Bot GPT 3.5 To isolate the variable "x", we need to perform the opposite operation on both sides of the equation.
First, we subtract 5.1 from both sides of the equation:
21.3 - 5.1 = x + 5.1 - 5.1
16.2 = x
Therefore, the solution to the equation is x = 16.2.
To verify this solution, we can substitute x = 16.2 back into the original equation:
21.3 = 16.2 + 5.1
21.3 = 21.3
Since the left side equals the right side, our solution is correct.
