Answer: x=-2 y=13
2(-2)+1=-3 check
-2-2=-4 check
Step-by-step explanation:
Horner's method:
2 1 -3
1 -2 -4
delta = det(
2 1
1 -2) = 2×-2 - 1 = -5
x = det(
-3 1
-4 -2)/-5 = (-2×-3-1×-4)/-5 = -2
y = det(
2 -3
1 -4)/-5 = (-8+3)/-5 = 1
Or by elimination
x = 2y - 4 from adding 2y=2y to second eqn
2(2y-4)+y=-3 by substituting for x in first.
4y-8+y=-3
5y=8-3=5
y=1
x=2y-4=2-4=-2
