2) m + 4 =1
3) 1 – t = 5
4) 4 – m = 1
5) 9 – y = 6
6) -5 + p = 2
7) -5 – p = 7
8) 8 = a – 5
Please jawab dikumpul besok nih
Tentukan selesian persamaan berikut
Jawaban:
1. x+3 = 7
x = 7-3
x = 4
2. m+4 = 1
m = 4-1
m = 3
3. 1-t = 5
-t = 5-1
-t = 4
t = -4
4. 4-m = 1
-m = 1-4
-m = -3
m = 3
5 . 9-y = 6
-y = 6-9
-y = -3
y = 3
6. -5+p = 2
p = 2+5
p = 7
7. -5-p = 7
-p = 7+5
-p = 12
p = -12
8. 8 = a-5
8+5 = a
13 = a
a = 13
