Look at Mia's work.

[tex]\[

\begin{aligned}

83+n & =110 \\

83+83+n & =110+83 \\

n & =193

\end{aligned}

\][/tex]

What was Mia's error?

A. Mia's work is correct.
B. Mia made an addition error when adding 110 and 83.
C. Mia only needed to add 83 to 110.
D. Mia should have subtracted 83 from both sides of the equation.

Answer :

Sure! Let's go through the steps to solve Mia's equation correctly.

Mia was solving the equation:

[tex]\[ 83 + n = 110 \][/tex]

Here's a step-by-step explanation of what should be done:

1. Identify the Operation: We need to solve for [tex]\( n \)[/tex]. The equation is currently [tex]\( 83 + n = 110 \)[/tex]. To isolate [tex]\( n \)[/tex], we need to undo the addition of 83.

2. Use the Inverse Operation: To undo the addition of 83, we should subtract 83 from both sides of the equation. This is the inverse operation.

3. Subtract 83 from Both Sides:
[tex]\[
83 + n - 83 = 110 - 83
\][/tex]

4. Simplify:
[tex]\[
n = 27
\][/tex]

So, the correct value for [tex]\( n \)[/tex] is 27.

Mia's Error: She added 83 to both sides instead of subtracting 83. This resulted in an incorrect step and solution.

Therefore, the correct step was to subtract 83 from both sides, and the correct value of [tex]\( n \)[/tex] is 27.
