tolong bantuannya ya kak

persamaan linier

1.
2/3 (2y - 3) = 1/2 (4y + 2) ....kalikan 6
4(2y - 3) = 3(4y + 2)
8y- 12 = 12y + 6
8y - 12y = 12 + 6
-4y = 18
y = -18/4 
y = - 4 ¹/₂

2.
(2y -5)/4 + 7/12 = (4y - 1)/3 ....kalikan 12
3(2y - 5) + 7  = 4(4y - 1)
6y - 15  + 7  = 16y - 4
6y - 8 = 16y - 4
6y -16y = 8 -4
-10y =  4
y =  - 2/5
