What is the solution to the linear system –4x + 2y = –56 and –3x – 6y = 33?Question 3 options:
(–9, 10)
(–9, –10)
(9, 10)
(9, –10)

  • solving systems by elimination -

    -12 x + 6 y = -168
    - 3 x - 6 y = 33
    ---------------------
    -15 x = -135
    x = +9

    -3*9 - 6 y = 33
    -27 -33 = 6y
    y = -10
    so (9,-10)
