Question

Find the value of a and b for which the given pair of linear equations have infinitely

many solutions: 4x + 5y = 2 ; (2a + 7b) x + (a + 8b) y = 2b – a + 1​

Answer 1

Answer: The answer is y = -(2a+7b)x/(a+8b) + (2b-a+1)/ (a+8b)

Step-by-step explanation:

4x+5y=2

5y = -4x + 2

y = -4/5x + 2/5

(2a+7b)x+(a+8b)y=2b-a+1

(a+8b)y = -(2a+7b)x + (2b-a+1)
