Question

1x/2-1y/3=32 x+y=26，Yx等于多少，y等于多少？

Answer 1

(1/2)x - (1/3)y = 32
[(1/2)x-(1/3)y]*6 = 32*6
3x-2y=192
x+y = 26
(x+y)*2 = 26*2
2x+2y = 52
由 3x-2y=192 和 2x+2y = 52 两者相加得到
(3x-2y)+(2x+2y ) = 192+52
5x=244
x=48.8
x+y = 26 => y = 26-x = 26-48.8
y=-22.8
最后得到，x=48.8, y =-22.8

Answer 2

希望对你有帮助！

Answer 3

(1/2)x一(1/3)y=32……(1)
x+y=26…………(2)
(1)X3+(2)得:
(5/2)ⅹ=122
ⅹ=48.8，
(2)一(1)X2得:
(5/3)y=一38
y=一22.8。
