The solution to the first pair of equal expressions is:
16x = 10(x + 1)
16x = 10x + 10
6x = 10
x = 10/6 = 1 and 2/3
The solution to the second pair of equal expressions is:
10(x + 1) = 26(+1) - 16
The left side is 10(x + 1) = 10x + 10
The right side is 26(+1) - 16 = 26-16 = 10
The equation now says 10x + 10 = 10
Subtract 10 from each side: 10x = 0
The solution to this pair of equal expressions is x = 0 .
I think I understand the weird question now. It's trying to say that
the first expression is equal to both the second and third expressions.
Let's try the first and the third:
16x = 26(+1) - 16
16x = 26 - 16
16x = 10
x = 10/16 = 5/8 = 0.625
Nope, that wasn't it.
The upshot of all my research is: I have no idea what the question is trying to say,
therefore no clue of what the actual question is, and no direction toward an answer.
