3×-5y=-14. 2×-8y=-2

Answer 1

Boa tarde Dany 

3x - 5y = -14
2x - 8y = -2 

6x - 10y = -28
6x - 24y = -6

-10y + 24y = -28 + 6 
14y = -22
y = -11/7

3x + 55/7 = -98/7
3x = -98/7 - 55/7 
3x = -153/7
x = -51/7 

Answer 2

3×-5y=-14(8)
2×-8y=-2(-5)

24x - 40y = - 112
-10x+40y = +10
      14x = - 102 ==> x = - 102/14 
=======================================================
2x - 8y = - 2  ==> 8y =  2 + 2x

8y =   2 + (-102)==> 112y= 28-102 ==> 112y= - 84
                   14

y = - 84 
       112
