Which equation models the problem and shows the correct solution?

The difference between [tex]x[/tex] and 89 is 7.

A. Write the equation as [tex]89 - x = 7[/tex] and subtract 7 from both sides. The answer is 82.

B. Write the equation as [tex]x - 89 = 7[/tex] and add 89 to both sides. The answer is 96.

C. Write the equation as [tex]x - 7 = 89[/tex] and add 7 to both sides. The answer is 96.

D. Write the equation as [tex]7 - x = 89[/tex] and subtract 7 from both sides. The answer is 82.

Answer :

To solve this problem, we're looking for an equation that accurately models the statement: "The difference between [tex]\(x\)[/tex] and 89 is 7."

The correct approach is to recognize that the word "difference" implies subtraction. So the equation that represents this situation is [tex]\(x - 89 = 7\)[/tex]. Here's how you solve it step-by-step:

1. Identify the Equation: We start with the equation [tex]\(x - 89 = 7\)[/tex].

2. Solve for [tex]\(x\)[/tex]: To isolate [tex]\(x\)[/tex], we need to eliminate the [tex]\(-89\)[/tex] by doing the opposite operation, which is addition.

3. Add 89 to Both Sides:
[tex]\[
x - 89 + 89 = 7 + 89
\][/tex]

4. Simplify:
[tex]\[
x = 96
\][/tex]

So, the equation [tex]\(x - 89 = 7\)[/tex] and the corresponding solution ([tex]\(x = 96\)[/tex]) correctly model and solve the problem.
