✔ 最佳答案
(5/4)y - 19 = 26
(5/4)y = 26 + 19
(5/4)y = 45
(5/4)y * (4/5) = 45(4/5)
y * (20/20) = (45/5) * 4
y * 1 = 9 * 4
y = 36

If you meant 5/(4y) - 19 = 26, then
5/(4y) - 19 = 26
5/(4y) = 45
5/45 = 4y
1/9 = 4y
y = 1/36

5/4(y) - 19 = 26
5y/4 = 26 + 19
5y = 4(45)
y = 180/5
y = 36

Presentation is incorrect.
I think that you may mean :-

(5/4) y - 19 = 26
5y - 76 = 104
5y = 180
y = 36

NOTE
-----------
5/4y does NOT = (5/4) y
5/4y DOES = 5 / (4y)

You will note from the incorrect answers that you are receiving that chaos reigns !

Brackets must be used to clarify question.

5/4y-19 =26
5/4y=26+19
5/4y=45
5/45=4y
(1/4)(5/45)=y
y= 1/36

5/4y - 19 = 26. add 19 under the 19 and 26 in the formula. now, you'll have this:

5/4y = 45

multiply both sides by 4/5 to cancel the 5/4 that's on the left. you should have this:

y = 45(4/5)

45 times 4 = 180. divide 180 by 5 and the answer will be 36.

5/4y-19=26
5/3y=26+19
=45
y=45/(5/3)
=27
