Question

2 1/4+5(1-y)=2(1/3-2y) berapa himpunan penyelesaian nya?

Answer 1

2 1/4 + 5 ( 1 - y ) = 2 ( 1/3 - 2y )
9/4 + 5 - 5y = 2/3 - 4y
29/4 - 5y = 2/3 - 4y
y = 79/12

Answer 2

2 1/4 + 5(1-y) = 2 (1/3 - 2y)
9/4 + 5 - 5y = 2/3 - 4y
-5y + 4y = 2/3 - 9/4 - 5
(samakan penyebutnya sehingga)
-60y/12 + 48y/12 = 8/12 - 27/12 - 60/12
-12y / 12 = -79/12
y = 79/12 =  6 7/12

begitu kah?
