Answer :

Certainly! Let's explore two expressions that both equate to 19.

### First Expression:
1. Start with the number 10.
2. Add 9 to it.

[tex]\[ 10 + 9 = 19 \][/tex]

So, the first expression is:
[tex]\[ 10 + 9 = 19 \][/tex]

### Second Expression:
1. Start with the number 20.
2. Subtract 1 from it.

[tex]\[ 20 - 1 = 19 \][/tex]

So, the second expression is:
[tex]\[ 20 - 1 = 19 \][/tex]

### Verification

Now, let's verify that both expressions indeed result in 19.

1. For the first expression:
[tex]\[ 10 + 9 = 19 \quad \text{which is true.} \][/tex]

2. For the second expression:
[tex]\[ 20 - 1 = 19 \quad \text{which is also true.} \][/tex]

Hence, we have two expressions:
1. [tex]\(10 + 9\)[/tex]
2. [tex]\(20 - 1\)[/tex]

Both of these expressions correctly result in 19.
