1-60. define a variable and then write and solve an equation for the problem below. remember that you can
use the 5-d process (described in the lesson 1.1.3 math notes box) to you get started. state your
solution in a sentence.
todd is 10 years older than jamal. the sum of their ages is 64. how old are todd and jamal?

5D process?  Gimme a break.

We'll skip the first box; the description of the problem is pretty self explanatory.

Define t as Todd's age, j as Jamal's age.

The description tells us

t = 10 + j

t + j = 64

Do.  We solve by substituting for t in the second equation,

10 + j + j = 64

2j = 54

j = 27

t = 10 + j = 37

Decide.  Not sure what I'm supposed to decide here; I decided I'm done.  Maybe this is where we check it.

37 = 10 + 27, good on that

27 + 37 = 64, good on that

Declare:

Jamal's age is 27 and Todd's age is 37.
