Answer 1

To determine how many equations have the same solution set, we can solve each equation and see if they lead to the same solution.

**Equation A:**
\[ 45(3f - 7) = 25(4f - 8) \]

Expanding both sides:
\[ 135f - 315 = 100f - 200 \]

Rearranging gives:
\[ 135f - 100f = 315 - 200 \]
\[ 35f = 115 \]
\[ f = \frac{115}{35} = \frac{23}{7} \]

**Equation B:**
\[ 59g - 2 = 79 \]

Adding 2 to both sides:
\[ 59g = 81 \]
\[ g = \frac{81}{59} \]

**Equation C:**
\[ -2(4 - 2h) = -3(1 - h) \]

Expanding both sides:
\[ -8 + 4h = -3 + 3h \]

Rearranging gives:
\[ 4h - 3h = -3 + 8 \]
\[ h = 5 \]

Now we have the solutions:
- Equation A: \( f = \frac{23}{7} \)
- Equation B: \( g = \frac{81}{59} \)
- Equation C: \( h = 5 \)

Since all three equations yield different solutions, none of the equations have the same solution set.

The correct response is:
**none**
