Using the linear combination method, what is the solution to the system of linear equations 7x-2y=-20 and 9x+4y=-6?
O (-3,2)
O (-2,3)
O (2, -3)
O (3,-2)

7x -2y + 20 =0 and 9x + 4y + 6 =0 are the solutions to the answer

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
