Question

Given the following system of equations, identify the type of system.

x + y = 6
y = 3 - x


consistent
inconsistent
equivalent

b

Answer 1

solve for y in both equations.

Answer 2

kk one sec

Answer 3

x + y = 6 solve for y
y = 3 - x already solved for y

y=-x+3 rearanged the above one.

Basicly get it in y=mx + b mode.


you got 3 cases now

1. if ms are different you got consistent
2. A. If m same and b same you got equivlient
B. if m same and b different then Inconsistent.

Answer 4

-3 and 9 ??

Answer 5

x + y = 6
y=6-x
------
y=-x+6
y=-x+3

Inconsistant

Answer 6

same m of -1 yet 2 different bs make it inconsistent.

Answer 7

so inconsistant ?

Answer 8

Yes inconsistent/ no solution
