Question

Find out the pair of linear equations 2x + 3y = - 12 and 3x + y = 13 is

consistent or inconsistent.​

Answer 1

Answer:

Your answer is here:-

Step-by-step explanation:

2x + 3y = -12

A1 = 2, B1 = 3, C1 = -12

3x + y = 13

A2= 3, B2 = 1, C2 = 13

Here A1/A2 is not equal to B1/B2.

So, the equation is inconsistent.

Hope it helps you.

Answer 2

consistent pair

Step-by-step explanation:

2x+3y= -12

i.e.2x+3y +12 =O ~ equation 1

3x+y=13

i.e.3x+y-13= O~ equation 2

here, 2/3 not = 3/1

i.e.a1/a2 not= b1/b2

therefore

it is consistent pair ,intersecting lines containing unique solution
