Question

10x-3y=36
2x+5y=-34
son sistemas de ecuaciones lineales

Answer 1

Procedimiento
10x-3y=36
2x+5y=-34...........multiplicamos por (-5) 
--------------
10x-3y=36
-10x-25y=170
-------------------
-28y=206
y= - 206/28
y = - 103/14


Hallamos x
10x-3y=36
10x - 3 (-103/14)=36
10x + 309/14 =36
10x = 36 -309/14
10 x =195/14
x= 195/(14*10)
x=195/140
x= 39/28
