Select all equations that can result from adding these two equations or subtracting one from the other.
equation 1: x + y = 12
equation 2: 3x - 5y = 4
(Select all that apply)

Step-by-step explanation:

x + y = 12 (1)

3x - 5y = 4 (2)

(1)*5 + (2) * 1 then,

5x + 3x = 60 + 4

8x = 64

x = 64/8

x = 8

from (1), 8 + y = 12

y = 4

apply(x,y)=(8,4) to these function.

-2x-4y = -32 no

-2x+6y=8 yes

answer;

the correct answer

just use google you beautiful person.

have a nice day < 3

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
