1. 6 (1/2y - 5/6) = 8 (1/4y + 1/2) + 2y 2. -3/4y = -3/8 3. Untuk persamaan 4(2y + 3) = 5y - 9,tentukan nilai-nilai berikut! a. 2y - 3 b. y^{2

1. 3y-5 = 2y+4+2y
3y-5-2y-4-2y = 0
-y-9 =0
y = -9

2. -3/4y = -3/8
y = -3/8 : -3/4
y = -3/8 × 4/-3
y = -12/-24 = 1/2

3. 8y+12 = 5y-9
8y-5y = -9-12
3y = -21
y = -7
a. 2y-3 = 2(-7)-3 = -14-3 = -17
b. y^2+1 = (-7)^2+1 = 49+1 = 50

4. 6p-14p+21 = 12p-9

Semoga membantu yaa:)
