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, we combine like terms on both sides:

7 + a > 5 + 6

Combining like terms:

7 + a > 11

Next, we subtract 7 from both sides:

a > 11 - 7

Simplifying:

a > 4

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