Answer:

x = -2

y = 6

Step-by-step explanation:

y = -3x

x + y = 4

the substitution method works nicely here because the first equation is already solved for 'y'

so we can substitute '-3x' for 'y' in the second equation:

x + (-3x) = 4

-2x = 4

x = -4/2

x = -2

now we can solve for y:

y = -3(-2)

y = 6
