Question

x+y=4 and x+4=5/2(y+4)​

Answer 1

Answer:

pata ni ha bc

Answer 2

Answer:

asper the question

x+y=48...(1)

x+4=5/2(y+4)

x+4=5y/2+20/2

x+4= take LCM.. 5y+20

2

2(x+4)=5y+20

2x+8=5y+20

2x-5y=20-8

2x-5y=12.......(2)

multiplying eq(1). by 2 & eq(2) by 1, we get..

2x+2y=96...(3)

2x-5y=12..(4)

Now subtracting eq (3) &(4).

2x+2y=96

2x-5y=12

(-) (+). (-)

7y=84

y=84/7

y=12

putting the value of y in eq (1)

x+y=48

x+12=48

x=48-12

x=36..
