✔ 最佳答案
3/4x -2(24-x) = 33x/4 -48 + 2x = 3
3x/4 + 2x = 3+48
3x/4 + 2x = 51
3x/4 = 51 - 2x
3x = 4(51 - 2x)
3x = 204 - 8x
3x + 8x = 204
11x = 204
x = 204/11
x =18.54

16.
4分3x-2(24-x)=3
3/4 x - 48 + 2x = 3
3/4x - 48 + 8/4x = 3
11/4x = 3 + 48
11/4x = 51
x = 51 / (11/4)
x = 51*4/11
x = 204/11
4分3x-2(24-x)=3
3/4 x - 48 + 2x = 3
3/4x - 48 + 8/4x = 3
11/4x = 3 + 48
11/4x = 51
x = 51 / (11/4)
x = 51*4/11
x = 204/11

4分3x-2(24-x)=3
(3/4)x+48+2x=3
2x+(3/4)x= - 45
(2/3/4)x= - 45
x = - (16/4/11)
(3/4)x+48+2x=3
2x+(3/4)x= - 45
(2/3/4)x= - 45
x = - (16/4/11)
