tolong bantu ya no 3 bagian c,d,e

c. 25 - 4y = 6y + 15
pindah ruas jadi
25 - 15 = 6y + 4y
10 = 10 y
1 = y

d.1/3x -2/3 = 2/3x - 13/3
pindah ruas jg
13/3 - 2/3 = 2/3 x - 1/3 x
11/3 = 1/3x
× = 11/3 ÷ 1/3 -> 11/3 × 3/1
x = 11

e. 1x + 3 -7/2 = 3/2 x + 3/2 -1/2 x -2
pindah ruas lg
1x - 3/2 x + 1/2 x = 3/2 -2 -3 + 7/2
2/2 x - 3/2 x + 1/2 x = 3/2 - 2/2 -3/3 + 7/2
x = 8/2 - 3/3
x= 24 /6 - 6/6
x = 18/6 = 3
