Question

Solve the following system of equations:
2x - 5y =22
-2x - 3y = 6
Answer
a.
(1, -8)
b.
(-9, -8)
c.
(-9, 3)
d.
(8, 9)

Answer 1

Add the two equations to get

2x - 5y =22
-2x - 3y = 6
-----------
0x - 8y = 28


So

-8y = 28


Solve this for y. Then use this solution to find x.

Answer 2

@jim_thompson5910 that value isn't in the answer set though. :)

I think something may be missing from the equations.

Answer 3

hmm that's odd...

Answer 4

probably a typo in the original equations?
