Final answer:
To solve the equation -50.9 + n = -53, we add 50.9 to both sides to find that n equals -2.1. Substituting this value back into the original equation confirms that it is the correct solution.
Step-by-step explanation:
To solve the equation -50.9 + n = -53, you would isolate the variable n by moving -50.9 to the other side of the equation. This is done by adding 50.9 to both sides of the equation. Therefore, the solution is:
- -50.9 + n + 50.9 = -53 + 50.9
- n = -2.1
After solving, we can quickly check that this is the correct solution. By substituting n with -2.1 into the original equation:
- -50.9 - 2.1 = -53
- -53 = -53
This confirms that our solution for n is correct.
