puts it on her desk before math class.

00:32

The card reads: “9x minus 7i greater than 3 times 3x minus 7u. [The equation being written out on the card]

the card. [Kathy looks happy]

00:48

On the right side of the inequality, she distributes the 3 to the 3x minus 7u, leaving 9x minus [The right side is highlighted]

00:54

21 u on the right side.

00:56

Subtracting 9x from both sides, she gets negative 7i greater than negative 21 u.

01:02

Dividing both sides by a negative 1, she remembers to flip the inequality sign the other way… [The inequality sign flips sides]

01:08

…getting 7i less than 21 u.

01:12

She then divides both sides by 7, to get i <3
