Given that
(1, 2, 3) = ((x, y, z)
x + 2y  3z = a
x  y + z = b
2x + 3y  2z = c
x + 2y  3z = a =1 + 4 + 9 = 12 = a
x  y + z = b = 1  2  3 = 4 = b
2x + 3y  2z = c = 2 + 6 + 6 = 10 = c
a = 12
b = 4
c = 10
I hope this helps!

First, use the Distributive Property on both equations: .5x + .5y + 1 = 0 .5x  .5y = 2 Now, take both equationi'm going to use the bottom oneto remedy for a variable (i will decide upon x). .5x  .5y = 2 .5x = 2 + .5y Divide all sides via half. X = 1 + y Now substitute x into the primary equation: .5x + .5y + 1 = 0 .5(1 + y) + .5y + 1 = 0 Use the Distributive Property. .5 + .5y + .5y + 1 = zero Add like terms. 1.5 + y = zero y = 1.5 Now alternative y into the primary equation: .5x + .5y + 1 = zero .5x + .5(1.5) + 1 = 0 .5x  .75 + 1 = zero Add like phrases. .5x + .25 = 0 .5x = .25 Divide either side through half of. X = .5 ok! So now you've gotten y = 1.5 and x = .5!

Sub in the given values into the system of equations and then determine a, b and c.
1 + 2(2)  3(3) = 1 + 4 + 9 = 12 = a
etc.
