Using mental math solve the inequality 7+a>5+6 in the solution set the variable a must be greater than what number
Subtracting 5 from both sides of the inequality gives us:
7 + a - 5 > 5 + 6 - 5
This simplifies to:
a + 2 > 6
Subtracting 2 from both sides gives us:
a > 4
Therefore, the variable a must be greater than 4 in the solution set.
