Single Variable
2x = 8
x = 4
x + y = 10
x- y = 6
(8, 2)
What monkey did I show you at the start?
Capuchin Monkey
3x + 4 = 14
x = 3
2x + 3y = 16
5x - 4y = -6
(2, 4)
What is an equation?
Statement with equal sign
7x + 8 = 9x + 8
x = 0
x + 3y = 6
2x + 8y = -12
(42, - 12)
Whats the condition (aka General Rule) to solve a system of equations?
# of equations = # of variables
100x = 99x + 10 - 9x
x = 1
x − 7y = −11
5x + 2y= −18
(-4, 1)
Why is graphing not the best method?
Cuz integral values/simplicity for graph aren't always there
9999(x-2x) = -9999
x = 1
Why do we need # of equations and # of variables to be equal?
Sohum's discretion lol
