解方程组x+1/3=2y 3(x+1)-y=16
![解方程组x+1/3=2y 3(x+1)-y=16](/uploads/image/z/1481031-63-1.jpg?t=%E8%A7%A3%E6%96%B9%E7%A8%8B%E7%BB%84x%2B1%2F3%3D2y+3%28x%2B1%29-y%3D16)
整理得:
① x + 1 = 6 y
② 3 ( x + 1 ) - y = 16
把②代入①得:
3 × 6 y - y = 16
18 y - y = 16
17 y = 16
y = 16 / 17
代入①得:
x + 1 = 6 × 16 / 17
x = 96 / 17 - 1
x = 79 / 17
∴ x = 79 / 19 ,y = 16 / 17
① x + 1 = 6 y
② 3 ( x + 1 ) - y = 16
把②代入①得:
3 × 6 y - y = 16
18 y - y = 16
17 y = 16
y = 16 / 17
代入①得:
x + 1 = 6 × 16 / 17
x = 96 / 17 - 1
x = 79 / 17
∴ x = 79 / 19 ,y = 16 / 17
