If you can’t answer all of them on time I recommend you to take a picture then write down the work that way you can say to the teacher these are the answers for the ones I left blank
It depends on which variable is eliminated.
If you multiply the second equation by -1 and eliminate the y:
3x - y = 7
-6x + y = -10
-3x = -3 or x = 1
If you multiply the first equation by -2 and eliminate the x:
-6x + 2y = -14
6x - y = 10
y = -4
Anything else to the problem?
