The number of cats is an illustration of inequalities and your neighbor has 4 cats before she bought the 2 new cats
Inequalities are expressions, numbers and mathematical statements that have unequal values when compared and/or evaluated
We start by representing the initial number of cats with x.
From the question, the new cats she bought are
New = 2
So, we have
x + New greater than 5
Rewrite properly as
x + New > 5
Substitute known values in the above inequality
x + 2 > 5
Subtract 2 from both sides
x + 2 - 2 > 5 - 2
Evaluate the right-hand side
x + 2 - 2 > 3
Evaluate the left-hand side
x > 3
The smallest integer number greater than 3 is 4
Hence, your neighbor has 4 cats before she bought the 2 new cats
