7x+4y=-34
  x=-2-2y

7(-2-2y)=4y=-34
-14-14y+4y=-34
-10y+-14= could you show me step by step please?

how did they get y=2
                 x=-6
-----------------------
7x+4y=-34
  x=-2-2y
7(-2-2y)+4y=-34
-14-14y+4y=-34
-10y-14= -34  ************  could you show me step by step please?
Add 14
-10y = -20
Divide by -10
y = 2
------------
x = -2-2y
x = -2 - 2*2
x = -6
