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)
If you do not wish to solve the problem, test the various combinations of x and y and find which one works. That might be quicker.
for example:
try (-9,10)
-4(-9) + 2(10) = -56????
36 + 20 = -56 No way
