Step-by-step explanation:
1) 15/60 = 3/12 = 1/4
2) 8/36 = 4/23
5 ( x + 3) = 6x - 3
5x + 15 = 6x - 3
x = 18 <====== this is the number

Answer:
k= -0.2
Step-by-step explanation:
3+2(5k-3)=7 (original)
3+10k-6=7 (distribute 2 in (5k-3))
9+10k=7 (combine like terms 3+-6)
10k=-2 (subtract 9 on both sides to isolate k)
k=-0.2 (divide 10 on both sides to get you're answer/isolate k)
