Translating a Phrase Into a Two-Step Expression

Step 1:

Let Molly’s age be x.

Thrice Molly’s age is 3x

Step 2:

20 years less than thrice Molly’s age is 3x – 20

So the two-step expression representing Sally’s age would be 3x – 20

Problem 2:

If Clara has 10 toys more than twice Capri’s number of toys, write a two-step expression to represent the same.

Step 1:

Let Capri’s number of toys be y.

Twice Capri’s number of toys = 2y

Step 2:

10 toys more than twice Capri’s number of toys = 2y + 10

So the two-step expression representing Clara’s number of toys would be 2y + 10
