Sure! Let's work on solving these problems step-by-step.

### Problem 1: [tex]\( 39.4 + (-7.2) \)[/tex]

1. Start with the number [tex]\( 39.4 \)[/tex].
2. You need to add [tex]\( -7.2 \)[/tex] to [tex]\( 39.4 \)[/tex].

When you add a negative number, it's the same as subtracting the positive version of that number.

3. So we perform the subtraction: [tex]\( 39.4 - 7.2 \)[/tex].

4. Subtracting [tex]\( 7.2 \)[/tex] from [tex]\( 39.4 \)[/tex] gives us:
[tex]\[ 39.4 - 7.2 = 32.199999999999996 \][/tex]

Thus:
[tex]\[ 39.4 + (-7.2) = 32.199999999999996 \][/tex]

### Problem 2: [tex]\( 7.9 - 49.35 \)[/tex]

1. Start with the number [tex]\( 7.9 \)[/tex].
2. You need to subtract [tex]\( 49.35 \)[/tex] from [tex]\( 7.9 \)[/tex].

3. Performing the subtraction:
[tex]\[ 7.9 - 49.35 = -41.45 \][/tex]

So:
[tex]\[ 7.9 - 49.35 = -41.45 \][/tex]

### Final Answers:

1. [tex]\( 39.4 + (-7.2) = 32.199999999999996 \)[/tex]
2. [tex]\( 7.9 - 49.35 = -41.45 \)[/tex]
