User: example of A system comprising two linear equations in two variables has a unique solution if and only if the straight lines represented by the equations are nonparallel

Weegy: using an example: if the straight lines are parallel then the 2 equations will be like this: 1) 3x + 6y 2) 6x+ 12y they will be at a multiple of each other resulting in the same solution. So for a unique solution you are gonna need a non parallel [ solution. ]

User: example Suppose the straight lines represented by a system of two linear equations in two variables are parallel to each other. Then the system has infinitely many solutions

User: example of a and b as square matrix

User: x - 3y = -6

Weegy: C. ?
mythmoh|Points 5309|

User: x - 3y = -6 5x + 3y = 42

User: is this a unique solution x - 3y = -6 5x + 3y = 42

Weegy: x = 3 and y = -4 so the ordered pair is (3,-4)

User: x - 3y = -6 5x + 3y = 42 what is x and y

x - 3y = -6
5x + 3y = 42
adding up equations the result is:
6x = 36
x = 36/6 = 6
6 - 3y = -6
-3y = -6 - 6 = -12
y = -12/-3 = 4
The solution for the system x - 3y = -6 5x + 3y = 42 is (6, 4)
