Question

Help Solve by elimination.
-4x +5y=14
3x +y=20

Answer 1

[-4x+5y=14]* 3
[3x+y=20] * -4
________________
-12x+15y=42
-12x-4x=-80
_______________-
19y=122
y=122/19

Answer 2

Hey thanks - it make more sense now.

Answer 3

No problem. 122/19 seems like a weird answer though so I'd double check. You can also plug in your y value into either equation to solve for x

Answer 4

y=11.09 repeating, x=10.36 repeating is what I come up with
