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.
