\[2u+v=-6\]
multiple 2nd eq by -3 and add thenm together

Answer 2

what do you get?

no, -u=1
so u=-1, do you see your mistakes

The v was eliminated in the subtraction step.

Answer 8

V=-5

Answer 9

does v=-5 and u=-1 work for both equations

Answer 10

you will find that v does not = -5 so check your math, actully so me your math and I'll help you understand your mistake.

Answer 11

2(-1)+v=-7
