Does anyone know how to do these ?

equation would have no solution is when the lines are parallel, i.e. they have the same slope and they don't overlap. Then there can be no points that are common to both lines. In case of this system of two linear equations, the two lines For example, 5x- 3y= 1 and 15x- 9y= 5 have no solution because A/B = D/E = -5/3.

Step-by-step explanation:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
