just add the two equations u will gt the value of y.try it
OpenStudy (anonymous):
-y = -5 - 2x
y = 5 + 2x
OpenStudy (anonymous):
Plug y into the second equation.
OpenStudy (anonymous):
-2x - (5+2x) = -1
OpenStudy (anonymous):
2x+(-2x)-y-y=-5-1

Or do what she said.

solve dis u will get y.then put the value of y in any one eqn.u will get x.
OpenStudy (wolf1728):
Add the 2 equations
A) 2x - y = -5
B) -2x - y = -1
-2y = -6
and it's easy to solve for y and for x
