Answer 1

x+(5/6+1/5)/(1/5)=6
x+(25/30+6/30)/(1/5)=6
x+31/30 * 5=6
x+155/30=6
x=6-155/30=180/30-155/30=25/30=5/6

[x+(5/6+1/5)]/(1/5)=6
x+(5/6+1/5)=6*5=30
x=30-(5/6+1/5)=30-(25/30+6/30)=30-31/30=(900-31)/30=869/30

Answer 2

x+(5/6+1/5)/(1/5)=6
x+(25/30+6/30)/(1/5)=6
x+31/30 * 5=6
x+155/30=6
x=6-155/30=180/30-155/30=25/30=5/6

[x+(5/6+1/5)]/(1/5)=6
x+(5/6+1/5)=6*5=30
x=30-(5/6+1/5)=30-(25/30+6/30)=30-31/30=(900-31)/30=869/30
