Mr. Jacob is 55 years old and Tony is 7 years old. In how many years will Mr. Jacob be 4 times as old as Tony? Please help me solve this.

real easy with algebra ....

55+x = 4(7+x)
55+ x = 28 + 4x
27 = 3x
x = 9

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)
