Linear Equations Single Var
Solve for x.
x = 4
all real numbers
trolled lol
What is the method when you plug the value of one variable in terms of the other in an equation?

2x + 5 = 11
x = 3
What is the method where you cancel out variables by adding or subtracting the 2 equations?
Elimination
x^2 - x -20 = 0
(x + 4)(x - 5)
34x = 60 + 8
x = 2
y = 4x
3y + 3x = 15
(1, 4)
3x^2 - 10x + 3 = 0
(3x - 1)(x - 3)
12x + 24 = 26
x = 1
3y + 3 = 21x
y + x = 7
(1, 6)
x^2 + 2x + 1 = 0
(x+1)(x+1)
Solve for x.
(4x + 1000000000000000 + 2x + 15y + 14xzy + 1348483x + 18928323y + 82309yxz + 828332839xyz + 19328130923831290389023832019380931839013809328329013890218329312x^2389023830923y^92839032809z^90830923)^0 + x = (0932830129238312093218x + 9083903218309312831209y + 8921813290138209312z)^0 + 13
x = 13
you got trolled bad lol
Why do we put the solution to 2 var equations as (something, something)
Point of intersection on coordinates.
10x^2 - 21x -10 = 0 + ((ewqkjoiwqejqeoiweweq^sjkhdsdjk)^0 - 1)
(5x + 2)(2x - 5)
