solve by substitution: x=5y - 2, 2x + y = -4

[buddy]

Solve the system using the substituation method...
x=5y - 2
2x + y = -4
not sure of what im doing?

To "solve by substitution", you substitute from one equation into the other. In your case, the first equation is already solved for "x=", so plug the other side of that equation, the "5x - 2", in for the "x" in the second equation:

. . . . .2(5y - 2) + y = -4

Can you take it from there?

y=0
x=0-2=-2
thnx
