Answer:
x = -7
y = 42
Explanation:
y = -6x
y = -8x - 14
substitute -6x in the second equation for y
-6x = -8x - 14
add 8x to both sides
2x = -14
divide both sides by 2
x = -7
----------------
substitute that in to the first equation to solve for y:
y = -6(-7)
y = 42
----------------------------------
check the math:
y = -8x - 14
42 = -8(-7) - 14
42 = 56 - 14
42 = 42
