To identify the pair of linear equations that have the same solution set, we can solve each pair to see if they yield equivalent equations.

1. **For the first pair:**
- \(3(m+1)=10\)
\[
3m + 3 = 10 \implies 3m = 7 \implies m = \frac{7}{3}
\]
- \(6n + 3 = 6 - n\)
\[
6n + n = 6 - 3 \implies 7n = 3 \implies n = \frac{3}{7}
\]

These do not have the same solution.

2. **For the second pair:**
- \(2(3g+5)-2g=2(4-g)\)
\[
6g + 10 - 2g = 8 - 2g
\]
\[
6g - 2g + 2g = 8 - 10 \implies 6g = -2 \implies g = -\frac{1}{3}
\]
- \(-\frac{36h}{6}=2\)
\[
-6h = 2 \implies h = -\frac{1}{3}
\]

These have the same solution.

3. **For the third pair:**
- \(4 = \frac{k}{2} + 5\)
\[
4 - 5 = \frac{k}{2} \implies -1 = \frac{k}{2} \implies k = -2
\]
- \(4j - \frac{14}{3} + 5 = 3\)
\[
4j + 5 - 3 = \frac{14}{3} \implies 4j + 2 = \frac{14}{3}
\]
\[
4j = \frac{14}{3} - 2 = \frac{14}{3} - \frac{6}{3} = \frac{8}{3} \implies j = \frac{2}{3}
\]

These do not have the same solution.

4. **For the fourth pair:**
- \(4k - 5 = 2k\)
\[
4k - 2k = 5 \implies 2k = 5 \implies k = \frac{5}{2}
\]
- \(8j - 2 = 3j\)
\[
8j - 3j = 2 \implies 5j = 2 \implies j = \frac{2}{5}
\]

These do not have the same solution.

Thus, the pair of linear equations that have the same solution set is:

**2(3g+5)−2g=2(4−g) and −36h/6=2.**
