User: x + y = 12
x - y = 10
What is the value of the x-determinant for the system shown?
Weegy: x + y = 12 x - y = 10 so x + y = 10 12 x - y = 10 y=10-x 12x-(10-x)=10 x=20/13 ...

1/2x +1/3y = 0 multiply 6 on both sides:
3x + 2y = 0 (equation 1)
1/4x - 1/2y = 8 multiply 4 on both sides:
x - 2y = 32 (equation 2)
adding up equation 1 and 2 the result is:
4x = 32
x = 32/4 = 8
(1/2)(8) + 1/3y = 0
1/3y = -4
y = -4(3) = -12
The solution for the system 1/2x +1/3 y = 0 1/4x - 1/2y = 8 is (8, -12)

5x - 3y - 10 = 0 (equation 1)
x + y - 7 = 0 multiply 3 on both sides:
3x + 3y - 21 = 0 (equation 2)
adding up equation 1 and 2 the result is:
8x - 31 = 0
8x = 31
x = 31/8
(31/8) + y - 7 = 0
y = 7 - 31/8 = 56/8 - 31/8 = 25/8
The solution set for the system 5x - 3y - 10 = 0 x + y - 7 = 0 is (31/8, 25/8)

x + y = 12
x - y = 10
adding up equations the result is:
2x = 22
x = 22/2 = 11
The value of x-determinant for the system x + y = 12 x - y = 10 is 11.
