Question

if equation 2x+3y=7 and (a-b)x+(a+b)y=3a+b-2 has no solution then find value of a and b​

Answer 1

Answer:

a= 5b OR a/b=5

Step-by-step explanation:

• 2x+3y=7 and (a-b)x+(a+b)y=3a+b-2
• 2x+3y-7=0 and (a-b)x+(a+b)y-(3a+b-2)=0

for no solⁿ:- a¹/b¹=a²/b²

• so, 2/3=(a-b)/(a+b)
• 3(a-b)=2(a+b)
• 3a-3b=2a+2b
• a= 5b OR a/b=5
