Answer :

Let's solve each equation step-by-step to determine the number of solutions.

### Equation 1:
[tex]\[ -4^x - 1 = 3^{-x} - 2 \][/tex]
This equation is a comparison of exponential functions with differing bases. Solving it analytically can be complex, typically requiring numerical methods or graphical analysis. Here let's outline the reasoning:

1. Graph Analysis: By plotting the functions [tex]\( -4^x - 1 \)[/tex] and [tex]\( 3^{-x} - 2 \)[/tex] on a graph, we can visually determine the points of intersection.
2. Behavior Analysis: For large positive [tex]\(x\)[/tex], [tex]\( -4^x \)[/tex] grows rapidly in the negative direction while [tex]\( 3^{-x} \)[/tex] approaches zero. For large negative [tex]\(x\)[/tex], [tex]\( -4^x \)[/tex] approaches 0 rapidly from the negative side while [tex]\( 3^{-x} \)[/tex] grows exponentially.

From such behaviors, it can be deduced these functions are likely to intersect at most at one point due to their contradictory growing behavior.

### Equation 2:
[tex]\[ 3^x - 3 = 2x - 2 \][/tex]
This can be transformed and analyzed by plotting or understanding the growth rates:
1. [tex]\(3^x\)[/tex] grows exponentially whereas [tex]\(2x\)[/tex] grows linearly.
2. Equating these and solving may yield at most two solutions based on the distinct growth rates.

### Equation 3:
[tex]\[ -3x + 6 = 2^x + 1 \][/tex]
This equation can again be solved using a similar method:
1. Graph Analysis: The straight line [tex]\(-3x + 6\)[/tex] with slope -3 will intersect the exponential curve [tex]\(2^x + 1\)[/tex] potentially at most once since the exponential [tex]\(2^x\)[/tex] grows faster than linear terms.
2. Behavior Analysis: As [tex]\(x\)[/tex] increases, exponentially behaves much more steeply than linear, indicating a single intersection is more plausible.

### Summarizing the Solution Findings:
- Equation 1: Possible 1 solution based on exponential behavior.
- Equation 2: Likely 2 solutions due to the exponential and linear intersection.
- Equation 3: 1 solution based on graph analysis.

### Order of Equations by Number of Solutions (Least to Greatest):
1. [tex]\( -4^x - 1 = 3^{-x} - 2 \)[/tex] (1 solution)
2. [tex]\( -3x + 6 = 2^x + 1 \)[/tex] (1 solution)
3. [tex]\( 3^x - 3 = 2x - 2 \)[/tex] (2 solutions)

Thus, the ordered equations based on the number of solutions from least to greatest are:

1. [tex]\( -4^x - 1 = 3^{-x} - 2 \)[/tex]
2. [tex]\( -3x + 6 = 2^x + 1 \)[/tex]
3. [tex]\( 3^x - 3 = 2x - 2 \)[/tex]

### Final Order:

[tex]\[ \begin{aligned} & -4^x - 1 = 3^{-x} - 2 \\ & -3x + 6 = 2^x + 1 \\ & 3^x - 3 = 2x - 2 \\ \end{aligned} \][/tex]
