Answer: (x,y) = (7,-3)
Step-by-step explanation:
-4x - 10y = 2.........(1)
-6x - 10y = -12.........(2)
Subtract (2) from (1)
-4x — (-6x) -10y — (-10y) = 2 — (-12)
-4x + 6x + 0 = 2 + 12
2x = 14
x = 14/2
x = 7.
Substitute 7 for x in (1)
-4(7) - 10y = 2
-28 — 10y = 2
-10y = 2 + 28
-10y = 30
y = 30/-10
y = -3.
(x,y) = (7,-3)
