Jawaban dan Penjelasan dengan langkah-langkah:
a) 3a-12=8-6a-2
3a+6a=8-2+12
9a=18
a=2
b) 2y+7=5y-11
2y-5y=-11-7
-3y=-18
y=6
c)
[tex]4-\frac{2}{p}=8+\frac{1}{2} \\-\frac{2}{p}=8+\frac{1}{2}-4\\-\frac{2}{p}=4\frac{1}{2} \\-\frac{2}{p}=\frac{9}{2} \\9p=-4\\p=-\frac{4}{9}[/tex]
d) 2t+7=5t-11
2t-5t=-11-7
-3t=-18
t=6
