real easy with algebra ....
55+x = 4(7+x)
55+ x = 28 + 4x
27 = 3x
x = 9
but grade 5 ????
make two colums of their ages, going up one at a time, until the first is 4 times the second
55 7
56 8
57 9
58 10
59 11
60 12
61 13
62 14
63 15
64 16  ah, 64 = 4(16) > 55+9 = 4(7+9)

I'm I pretty smart student and the answer is correct.
Algebra:
55+x = 4 (7+x)
55+ x = 28 + 4x
27 = 3x
x = 9
And if your grade 5

60 12
61 13
62 14
