n \times (n + 1) = even \times odd = even. n×(n+ 1) = even×odd = even. Similarly, if n n is odd, then n + 1 n+1 is even and hence. n \times (n + 1) = odd \times even = even. n×(n+ 1) = odd ×even = even. Therefore, the numerator is always even and \frac {n (n + 1)}2 2n(n+1) is always a positive integer.

To find the generic solution, return to one of the original equations and solve for [latex]y [/latex]. [latex]\begin {array} {l}3x+4y=12\hfill \\ \text { }4y=12 - 3x\hfill \\ \text { }y=3-\frac {3} {4}x\hfill \end {array} [/latex] So the solution to this system is [latex]\left (x,3-\frac {3} {4}x\right) [/latex].
