[26.2x+3y=7],[2ax+(a+b)y=28]

Write the set of values of a and b for which the following system of equations has infinitely many solutions.2x+3y=7,quad 2ax+(a+b)y=28

If the system of equations 2x+3y=7, 2ax+(a+b)y=28 has many solutions, then _______

If the system of equations 2x+3y=7,quad 2ax+(a+b)y=28 has infinitely many solutions,then a=2b (b) b=2a(c)a+2b=0 (d) 2a+b=0

If the system of equations 2x+3y=7,\ \ \ 2a x+(a+b)y=28 has infinitely many solutions, then (a) a=2b (b) b=2a (c) a+2b=0 (d) 2a+b=0

Write the set of values of a and b for which the following system of equations has infinitely many solutions. 2x+3y=7,\ \ \ \ 2a x+(a+b)y=28

Find the values of a and b for which the following pair of equations have infinitely many solutions: (i) 2x + 3y = 7 and 2ax + ay =28-by (ii) 2x + 3y =7, (a-b) x + (a +b) y= 3a + b-2 (iii) 2x - (2a + 5) y =5, (2b +1) x - 9y =15

Values of a and b so that system of equations 2x + 3y = 7 and 2 ax + (a +b) y = 28 has infinitely many solutons are

If the system of equations 2x + 3y = 7 and 2ax + (a + b) y = 28 has infinitely many solutions, then which one of the following is correct ?

Find the values of a and b for which the following system of equations has infinitely many solutions : 2x+3y =7 2ax +ay = 28 - by

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