First one is 6y + 48 (6*y + 6*8)

Second is 19y + 5 Work left to right.

Third one, assume y is the difference in feet.

103 = x + y

10*(103) = 10*(x + y)

1030 = 10x + 10y

first one is obviously 6y+48 because distributive 6(y+8) 6 times y and 6 times 8

Second is 19y+negative7 because you do like terms which would be rewritten as 7y+12y-1+6 you CAN NOT do subtraction so you would do SAME CHANGE OPPOSITE which would be changed to 7y+12+negative1+negative 6 so your final answer is 19y+negative 7...not sure about third one but I THINK its 10(x+103) good luck <3
