To determine which pair of linear equations have the same solution set, we can simplify each equation and look for those that yield the same solution for their respective variables.
-
First Pair:
\(4k - 5 = 2k\)
Simplifying:
\(4k - 2k = 5\)
\(2k = 5\)
\(k = \frac{5}{2}\)\(8j - 2 = 3j\)
Simplifying:
\(8j - 3j = 2\)
\(5j = 2\)
\(j = \frac{2}{5}\)
Not the same solution set. -
Second Pair:
\(3(m + 1) = 10\)
Simplifying:
\(3m + 3 = 10\)
\(3m = 7\)
\(m = \frac{7}{3}\)\(6n + 3 = 6 - n\)
Simplifying:
\(6n + n = 6 - 3\)
\(7n = 3\)
\(n = \frac{3}{7}\)
Not the same solution set. -
Third Pair:
\(2(3g + 5) - 2g = 2(4 - g)\)
Simplifying:
\(6g + 10 - 2g = 8 - 2g\)
\(4g + 10 = 8 - 2g\)
\(4g + 2g = 8 - 10\)
\(6g = -2\)
\(g = -\frac{1}{3}\)\(-\frac{36h}{6} = 2\)
Simplifying gives us:
\(-6h = 2\)
\(h = -\frac{1}{3}\)
Same solution set: \(g = h = -\frac{1}{3}\) -
Fourth Pair:
\(4 = k^2 + 5\)
Rearranging:
\(k^2 = -1\)
No real solution.\(4j - 14 + 5 = 3\)
Rearranging:
\(4j - 9 = 3\)
\(4j = 12\)
\(j = 3\)
Not the same solution set.
Based on the simplifications, the pair of linear equations that have the same solution set is:
2(3g + 5) - 2g = 2(4 - g) and -36h/6 = 2.
