The equations are illustrations of conditional statements or transitive property
The complete statement is: "If m + n = 2k and 2k = 2n + 8, then m + n = 2n + 8"
<h3>How to complete the transitive property</h3>
The equations are given as:
m + n = 2k and 2k = 2n + 8
Substitute 2n + 8 for 2k in m + n = 2k
So, we have:
m + n = 2n + 8
Hence, the complete statement is:
"If m + n = 2k and 2k = 2n + 8,
then m + n = 2n + 8
