using mental math, solve the inequality 7 + a > 5 + 6. in the solution set, the variable a must be greater than what number?

Answer 1

To solve the inequality 7 + a > 5 + 6, we can simplify both sides:

7 + a > 5 + 6
7 + a > 11

Now, we can subtract 7 from both sides to isolate the variable a:

a > 4

Therefore, in the solution set, the variable a must be greater than 4.
