I need some help figure out the worksheet... Help me on the "?"

1. 15d - 8 + 6d -9 = ? = 21d - 17

2.8x -3y + 6x -4y ? = 14x - 7y

3. Siti is 2h years old. Her brother is 7 years older than her. Find their total age?
I don't know how to write the front part. I saw the answers is (4h + 7 )years

lol don know what question 1 and 2 is asking about but i think is left equal right

qns 3 is..
Siti age : 2h
Her brother age : 2h+7
therefore total age is 2h+(2h+7)= (4h+7)

i think is
2. 8x-3y+6x-4y=8x+6x-3y-4y=14x-7y
1. 15d-8+6d-9=15d+6d-8-9=21d-17
