please kk dijawab beserta caranya

| 4 | (-3,-2) | x = 3 | x = 5 | (1,-2) |
| 5 | (-2,4) | x = 5 | x = 3 | (-6,4) |
| 6 | (-1,2) | y = 1 | y = -2 | (-1,-4) |
| 7 | (4,-3) | y = -1 | y = 2 | (4,3) |

4)
2(3) - (-3) = 9
2x - 9 = 1
2x = 1 + 9
2x = 10
x = 10/2
x = 5

5)
2x - (-2) = 2x + 2
2(3) - (2x + 2) = -6
6 - 2x - 2 = -6
-2x + 4 = -6
-2x = -6 - 4
-2x = -10
x = -10/-2
x = 5

6)
2(1) - 2 = 0
2y - 0 = -4
2y = -4
y = -4/2
y = -2

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