Question

Fan and medal?
Solve the system by substitution.

2.5 - 3y = -13
3.25 - y = -14

Answer 1

okay so what all do you understand about substitution?

Answer 2

Nothing whatsoever ._. I suck at math and I'm really behind from my class.

Answer 3

alright substitution is easy
first you need to multiply the bottom by negative 3

Answer 4

then you need to add the equations together

Answer 5

so it will be 2.5x - 3y = 13
+9.75x +3y = 42

Answer 6

Okay.

Answer 7

what do you get when you add them together?

Answer 8

12.25x + 6y + 55

Answer 9

=*

Answer 10

does it say anywhere what y or x equals?

Answer 11

No, I posted everything

Answer 12

wait i accidentally added X's to it
it should be 12.25 + 6y = 55

Answer 13

Oh, okay. So don't add the x's?

Answer 14

well i looked at the equation and saw that there weren't X's but add them either way

Answer 15

Oh. Okay, gotcha. So what next?

Answer 16

so you can subtract 12.25 from the left and from the right leaving you with 6x=42.75

Answer 17

and you can divide the 42.75 by 6 leaving you with x=12.25

Answer 18

X should be Y sorry

Answer 19

anyways your answer should be y = 12.25

Answer 20

Oh, woe. Okay! Thank you :)

Answer 21

no problem :D
