Question

Solve the system of equations by the substitution method.

{x+y=-24
{ y=-5x


Show work please!!

Answer 1

We can substitute the second into the first, this gives:

x -5x = -24 =>
-4x = -24
x = 6

fill in this x value in the second equation:

y = -5*6 = -30

So the solution is x=6, y=-30
