Question

quien lo resuelve(metodo de igualacion) 2x+3y=-12 y 4x-5y=-2

Answer 1

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

2x+3y= -12
x= (-12-3y)/2

4x-5y= -2
x= (-2+5y)/4


(-12-3y)/2= (-2+5y)/4

2(-12-3y)= -2+5y

-24-6y= -2+5y

5y+6y= -24+2
11y= -22
y= -22/11
y= -2


x= (-2+5y)/4
x= (-2+5(-2))/4
x= (-2-10)/4
x = -12/4
x= -3

Salu2.

Suerte... :)
