1.tentukan himpunan penyelesaian persamaan berikut. A. 1 per 2 [a-6] = 5 B. x - 1 per 2 = 6 + 1 per 2 x C. [p - 3] = 2 per 3 [p + 4] D. 2 y - 11 per 3 = 5 y

A.) 1/2 [a-6]
≈ 1/2a-1/2×6
≈ 1/2a-3

B.) x-1/2 = 6+1/2
≈ x-1/2 = 7/2
≈ x-1 = 7
≈ x=7+1
≈ x=8

C.)[p-3] = 2/3[p+4]
≈ p-3 = 2/3p + 8/3
≈ 3p-9 = 2p+8
≈ 3p-9 = 8+9
≈ p=17

D.)2y-11/3 = 5y+5/5
≈ 2y-11/3 = 5(y+1)/5
≈ 2y-11/3 = y+1
≈2y-11 = 3y+3
≈2y-3y = 3 +11
≈ -y=14
≈ y=-14
