Question

If 2a = b, the pair of equations ax + by = 2a2- 3b2, x + 2y = 2a - 6b possess:​

Answer 1

Answer:

ANSWER

ax+by = 2a2−3b2,   x+2y=2a−6b

Given, 2a=b

Now, ax+by=2a2−3b2

ax+2ay=2a2−3(2a)2

a(x+2y)=−4a2

x+2y=−4a

Also, the other equation is, x+2y=2a−6b

Since, the coefficients of x and y for both the equation are same. There will be infinite solutions for this set of equations.
