The equations 3x + 2y = 6 and 3x + 2y = 12 are inconsistent. A linear system is inconsistent if it has no solution, and otherwise, it is said to be consistent. [7] When the system is inconsistent, it is possible to derive a contradiction from the equations, that may always be rewritten as the statement 0 = 1. For example, the equations
Reflexivity: for every a, one has a = a.; Symmetry: for every a and b, if a = b, then b = a.; Transitivity: for every a, b, and c, if a = b and b = c, then a = c. [7] [8]Substitution: Informally, this just means that if a = b, then a can replace b in any mathematical expression or formula without changing its meaning.
[1] [2] In order to make mileposts consistent with the real mileage, every milepost beyond the equation would need to be moved. [3] For example, an equation of 7.6 back = 9.2 ahead means that the feature does not have any section between mile 7.6 and mile 9.2, and the distance between mileposts 7 and 10 is only 1.4 miles. This would usually be ...
The partial sums of the series 1 + 2 + 3 + 4 + 5 + 6 + ⋯ are 1, 3, 6, 10, 15, etc.The nth partial sum is given by a simple formula: = = (+). This equation was known ...

Some Republican senators say they're ready to fight for their role to advise and consent on President-elect Donald Trump's Cabinet picks.
In mathematics, the infinite series 1 / 2 + 1 / 4 + 1 / 8 + 1 / 16 + ··· is an elementary example of a geometric series that converges absolutely. The sum of the series is 1.
