Solve by substitution:
2x-y = -5
-x+-y =10

Sagot :

2x-y=-5
-x-y=10
3x=-15
x=-5
-10-y=-5
-y=-5+10
-y=5
y=-5

{2x-y = -5 => -y=-5-2x    /*(-1)    y=2x+5
{-x+-y =10

Substitute y in the second equation:

-x-y=10

-x-(2x+5)=10

-x-2x-5=10

-3x-5=10    /+5

-3x=15     /:(-3)

x=-5

y=2x+5=2*(-5)+5=-10+5=-5

y=-5

Solution:   (-5; -5)
