Step-by-step explanation:
Given two equations are ,
- 21x -3y = 7
- ( a + b)x - ( a + b -3)y = 4a + b .
We need to find the value of a and b for which the system of equations has infinitely many solutions .
For full solution kindly refer to the attachment .

• The system of equations has only one solution if ,
=> a1/a2 ≠ b1/b2
• The system of equations has no solution if ,
=> a1/a2 = b1/b2 ≠ c1/c2 .
