HELP PLEASE I DONT UNDERSTAND

Which ordered pair is a solution to the system of linear equations? 2x + 3y= 6 –3x + 5y = 10

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)

Asequence is defined recursively using the formula f(n + 1) =f(n) - 5. which sequence could be
