Question

for what values of p and q will be the following pair of linear equations has infinitely many solutions 4x+5y= 2 (2p+7q)X+(p+8q)y=2q-p+1
​

Answer 1

Answer:

If the equations have many solution, then a1/a2=b1/b2=c1/c2. ... have infinitely many solutions 4x+5y=2, (2p+7q)x+(p+8q)y=2q-p+ 1. 2.
