Question

The system of linear equations 4x+2y=7 and 2x+y=6 has

Answer 1

A1/a2=b1/b2=c1/c2: many solutions. A1/a2=b1/b2not equals to c1/c2:unique solutions. A1/a2not equals to b1/b2 not equals to c1/c2:no solution

Answer 2

Answer:

it has a unique solution

Step-by-step explanation:

given the equations 4x + 2y = 7

and 2x + y = 6

if a1/a2 = b1/b2 = c1/c2 , then the system of equations have infinitely many solutions. the two  equations will be parallel lines.

if a1/a2 = b1/b2 ≠ c1/c2, then the graph intersect at one point and have a unique solution

if a1/a2 ≠ b1/b2, then there is no solution .

here a1/a2 = b1/b2 ≠ c1/c2

that is 4/2 = 2/1 ≠7/6

therefore it has a unique solution.
