The solution for 7x - 3y = 4 , 2x - 4y = 1 is (13/22, 1/22) .

2x - 4y = 1

x = (1 + 4y)/2

put x = (1 + 4y)/2 in equation 1

7*(1 + 4y)/2 - 3y = 4

7 + 28y - 6y = 8

22y = 1

y = 1/22

x = (1 + 4*1/22)/2

x = 26/22*1/2

x = 13/22

The x-coordinate of the solution for y = 3 -1/2x , 3x + 4y = 1 is - 11 .

put equation 1 in equation 2 ,

3x + 4(3 - 1/2x) = 1

3x + 12 - 2x = 1

x = 1 - 12

x = -11

Given the system of equations, the y-coordinate of the solution for 5x - 4y = 7 , x = 5 -0.5y is 36/13 .

put x = 0.5 - 0.5y in equation 1

5(5 - 0.5y) - 4y = 7

25 - 5/2y - 4y = 7

50 - 5y - 8y = 14

-13y = -36

y = 36/13

The y-coordinate of the solution for 5x - 4y = 7 , x = 5 -3/2y is 36/23 .

Put x = 5 - 3/2y in equation 1

5(5 - 3/2y) - 4y = 7

25 - 15/2y - 4y = 7

50 - 15y - 8y = 14

-23y = -36

y = 36/23
