You are 34 years old

Step-by-step explanation:

Because, 34-17=17

17 is half of 34.

2x+20=y

y-17=0.5y

+17    +17

y=0.5y+17

2(0.5y+17)+20=0.5y+17

y+34+20=0.5y+17

y+54=0.5y+17

y=34

37 years old

Step-by-step explanation:

17 years before you are half age then I plus 20 years to 37 years, you said you am now, you are not before. You said you bigger your Daughter twice, so 37 multiply 2 equal 74, so your daughter 37 years old and you are 74 years old.
