Question

Write the number of solutions of the following pair of Linear equations 3x-7y=1 and 6x+14y-3=0

Answer 1

•3x-7y=1......(i)

•6x+14y-3......(ii)

•a1=3,b1=-7,c1=-1.

•a2=6,b2=14,c2=-3.

•a1/a2=3/6=1/2.

•b1/b2=-7/14=-1/2.

•Here a1/a2 is not equal to b1/b2.

•Hence we can say that the given equations has unique solutions with the graph intersecting.

Answer 2

Answer:

it have no solution

Step-by-step explanation:

A1 / A2 = 3/6 = 1/2

B1 / B2 = -7/-14 = 1/2

C1 / C2 = 1/3

A1 / A2 = B1 / B2 not equal to C1 / C2;

it have no solution
