Select the correct choices that belong in the blank for the system of equations shown below.

24x - 39 = 165

-6x +13y = -51

in order to solve this system by elimination, stacy by then, when she adds the equations together, the x terms will cancel.

1c) the number 131 is a term in the sequence defined by the explicit rule f(n)=5n-4. which term in the sequence is 131? 2a) write the first four terms of the function f(n)=n^2-1 2b) what is the 10th term of the sequence defined by the explicit rule f(n)=n^2-1 2c) the number 224 is a term in the sequence defined by the explicit rule f(n)=n^2-1. which term in the sequence is 224?
