    Around 3000 BCE, the Sumerians developed a numerical system based on the sexagesimal system (base 60), which is still in use for measuring time (seconds, minutes, and degrees in a circle) today. They also made strides in geometry, algebra, and arithmetic.

    Because they got the value of y in the first equation which is 3 so instead of writing y with the first equation they multiplied by 3 aka the value of y
