Question

X+1/(x+7)+6=1/2 and find y if 5/x+y=1

Answer 1

Answer:

x+1/x+7+6=1/2

LCM

x+1+6(x+7)/x+7=1/2

x+1+6x+42=1/2(x+7)

7x+43=1/2(x+7)

2(7x+43)=x+7

14x+86=x+7

14x-x=7-86

13x=-79

x=-79/13

given,

5/x+y=1

5/-79/13+y=1

5/-79+13y/13=1

65=-79+13y

13y=65+79

13y=144

y=144/13

y=11.07

Answer 2

Answer:

x=11, y=6/11

Step-by-step explanation:

x+1/(x+7)+6=1/2

Now cross multiplication

=2(x+1)=1((x+7)+6)

=2x+2=x+7+6

=2x+2=x+13

=2x-x=13-2

=x=11

Now, 5/x+y=1

5/11+y=1

y=1 - 5/11

y=11/11 - 5/11

y=6/11
