Question

10×-3y=13 2×-7y=9 resolver esta ecuacion​

Answer 1

Respuesta:

x=1 y=-1

Explicación paso a paso:

10x-3y=13

2x-7y=9

------------------------------------------

-5(2x-7y) = -5(9)

-10x+35y= -45

10x - 3y = 13

-10x+35y=-45

32y = -32

   y =  -1

------------------------------------------

10x-3(-1)=13

10x+3=13

x=1
