3x = - 4y 3x = -4y 3x + 4y = 0 | 5
x = - 4y / 3 x = -4y / 3 5x - 6y = 38 | -3
---------------------------
5x - 6y = 38 5 (-4y / 3) -6y = 38 15x + 20y = 0
x = ( 38 + 6y ) / 5 (-20y / 3) - 6y = 38 -15x + 18y = -114
(-20y - 18y ) / 3 = 38 ---------------------------
x = x -38y = 114 38y = -114
-4y / 3 = (38 + 6y ) / 5 y = 114 / -38 y = -114 / 38
- 20y = 114 + 18y y = -3 y = -3
- 38y = 114
y = 114 / - 38 x = -4y / 3 x = -4y / 3
y = -3 x = -4 (-3) / 3 x = -4(-3) / 3
x = 4 x= 4
x = - 4y / 3
x = -4 ( -3 ) / 3
x = 4
