The question given is slightly wrong.
The given pair of equations are x+2y-5=0 and -3x-6y+15=0
Answer:
Given pair of equations x+2y-5=0 and -3x-6y+15=0 have infinitely many solutions.
Step-by-step explanation:
Pair of equations:
- The pair of equations ax+by = c and lx+my = n have infinitely many solutions if a/l = b/m = c/n
- Given pair of equations are
x+2y-5=0 and -3x-6y+15=0
x+2y = 5 and -3x-6y=-15
Compare the coefficients
1/-3, 2/-6, 5/-15
1/-3, 1/-3, 1/-3
All are equal
Since 1/-3 = 1/-3 = 1/-3
So, the given pair of equations has infinitely many solutions.
