Question 1001623: Tom is 4 times as old as Todd. In 5 years Tom's age will be 1 year less than 3 times as old as Todd. How old is Tom?
My work so far:
I have been working on the problems for this question and I figured out that 4x is what Tom would be and I was looking at a previous question and was confused as to how the particular numbers are plugged in. I was working for a while too.

.
D=Todd's age; M=Tom's age=4D
In 5 years, Todd age= D+5
In 5 years, Tom's age=M+5
.
(M+5)-1=3(D+5) Substitute for M (M=4D)
4D+5-1=3D+15
4D+4=3D+15
D=11
ANSWER 1: Todd is eleven years old.
.
M=4D=4(11)=44
ANSWER 2: Tom is 44 years old.
.
CHECK:
(M+5)-1=3(D+5)
(44+5)-1=3(11+5)
49-1=3(16)
48=48
