Question

2x + 3y = -12 4x-5y=-2 metodo reduccion

Answer 1

Explicación paso a paso:

2x+3y= -12

4x-5y= -2

(2x+3y= -12)(-2)= -4x-6y= 24

-4x-6y= 24

4x-5y= -2

——————

-11y= 22

y= 22/-11

y= -2

2x+3y= -12

2x+ 3(-2)=-12

2x-6= -12

2x= -12+6

x= -6/2

x= -3

comprobación:

2x+3y= -12

2(-3)+3(-2)=-12

-6-6=-12

-12=-12

4x-5y= -2

4(-3)-5(-2)= -2

-12+10=-2

-2=-2
