✔ 最佳答案

(5/2)x + (1/4)x = (11/4) +x

4[(5/2)x + (1/4)x = (11/4) +x]

(20/2)x + (4/4) x = (44/4) + 4x

10x + x = 11 + 4x

11x-4x=11

7x=11

7x/7=11/7

x=11/7

(5/2)x+(1/4)x=11/4+x
(11/4)x=(11/4)+x
(7/4)x=11/4
7x=11
x=11/7
x=1 4/7

(5/2)x + (1/4)x = 11/4 + x
4(5x/2 + x/4) = 4(11/4 + x)
10x + x = 11 + 4x
11x - 4x = 11
7x = 11
x = 11/7
x = 1 4/7

you mean: 5x/2 +x/4= 11/4 +x ?
then :
11x/4 = 11/4 + x
11x/4 - 4x/4 = 11/4
7x/4 = 11/4
7x=11
x=11/7

Question is incorrectly presented.
Do you mean :-
(5/2) x + (1/4) x = (11/4) + x ??????
10x + x = 11 + 4x
7x = 11
x = 11/7
