Question

21.3=x+5.1

Answer 1

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.
