[2x+3y=7],[(a-b)x+(a+b)y=3a+b-2]

Find the values of a and b for which the following system of equations has infinfinitely many solutions: 2x+3y=7,quad (a-b)x+(a+b)y=3a+b-2

2x+3y=7(a+b)x+y(2a-b)=3(a+b+1) find the value of a+b

2x + 3y =7 , (a + b ) x + ( 2a - b ) y = 21 .

Find the value of a and b for which the following system of equations has infinite number of solutions. 2x + 3y = 7, (a + b) x + (2a - b) y = 3 (a + b + 1 ) .

Find the values of a and b for which the following system of linear equations has infinite number of solutions: 2x-3y=7,quad (a+b)x-(a+b-3)y=4a+b

For what values of a and b does the following pair of linear equations have infinite number of solution ? 2x+3y=7, a(x+y)-b(x-y)=3a+b-2

If 2x-3y=7 and (a+b)x-(a+b-3)y=4a+b represent coqucident lines,then a and b satisfy the equation?

If the system of equations 2x+3y=7,\ \ \ \ (a+b)x+(2a-b)y=21 has infinitely many solutions, then

2x + 3y = 7 , (a+b + 1 )x + (a + 2b + 2) y = 4 (a + b ) + 1
