492. A lot of barrage_1

The live stream fell into stagnation again.

On this end, Zhang Yanping stared at the live stream, unable to suppress his snickers.

Dying of laughter!

What linear equations of several variables? Qiaoqiao learned so quickly that she now knows how to solve one-variable linear equations? So does that mean she'll soon be able to solve two-variable linear equations—

Wait a minute!

He suddenly realized: how do you solve two-variable linear equations again?

Zhang Yanping's expression gradually became blank.

That is to say, he, Zhang Yanping, a university graduate of five years, had already returned all his knowledge?

Meanwhile, the bullet comments were just Goose Goose Goose Goose Goose Goose—

[Hahaha, hiccup]

[Hahaha, laughing so hard I'm crowing!]

[Dying laughing. What kind of divine child is this, can't do equations of several variables?]

[I mean, humble as I am, having just finished my freshman year, I still know how to solve two-variable linear equations, kinda proud]
