doy corona al que me responda a mas tradar mañana

Answer 1

X+y=2
X=6+y
6+y+y=2
6+2y=2
2y=2-6=-4
y=-2
X+(-2)=2. x-2=2. X=2+2=4
X=4. Y= - 2

X+2y=3
2x-y=1
X=3-2y
2(3-2y)-y=1
6-4y-y=1
6-5y=1
-5y=1-6. Y=-5/-5=1
2x-1=1. 2x=1+1. X=2/2=1
X=1. Y=1


X+2y=3
5x-3y=-11
X=3-2y
5(3-2y)-3y=-11
15-10y-3y=-11
15-13y=-11. -13y=-11-15. y=-26/-13=2
X=3-2(2)=3-4=-1. X=-1. Y=2


2x+y=5
X+3y=5
Y=5-2x
X+3(5-2x)=5
X+15-6x=5
-5x+15=5. -5x=5-15=-10. x=2
Y=5-2(2)=5-4=1. X=2. Y=1
