Question

Tentukan penyelesaian persamaan berikuta!!!tolong jawab dong pake cara yaa.

Answer 1

1. 2k + 3 = 11 2k = 11 - 3 2k = 8 k = 4 2. -7z = 3z - 30 -7z-3z= -30 -10z= -30 z = 3

Answer 2

1) 2k + 3 = 11
2k = 11-3
2k = 8
k = 4
2) -7z = 3z - 30
-7z - 3z = -30
-10z = -30
z = 3
3) 4d + 6 = d
4d - d = -6
3d = -6
d = -2
4) 6m -2 = 2m - 8
6m - 2m = -8 + 2
4m = -6
m = -3/2
5) 3m + 4 = 22
3m = 22-4
3m = 18
m = 6
6) 3t + 6 = 5t + 7
3t - 5t = 7 - 6
-2t = 1
t = -1/2
7) 5p - 1 = 4
5p = 5
p=1
8) 4z + 3 = 2z + 15
2z = 12
z = 6
9) 2q - 3 = 11
2q = 14
q = 7
10) 5s - 4 = 3
5s = 7
s = 7/5
