[" 23."2x-3y=7],[quad (a+b)x-(a+b-3)y=4a+b]

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

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 2x-3y=7" and "(a+b)x-(a+b-3)y=4a+b represent coincident lines, then a and b satisfy the equation :

If 2x-3y=7 and (a+b)x-(a+b-3)y=4a+b represent coincident lines, then a and b satisfy the equation (a) a+5b=0 (b) 5a+b=0 (c) a-5b=0 (d) 5a-b=0

If 2x-3y=7 and (a+b)x-(a+b-3)y=4a+b represent coincident lines,then a and b satisfy the equation a+5b=0 (b) 5a+b=0 (c) a-5b=0 (d) 5a-b=0

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

2x + 3y = 7& (a-b)x+ (a + b) y = 3a + b-2

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

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