That's more than 12 decimal places but it's all I remember off-by-heart.
Answer:
9) e=-40 10) k=9
Step-by-step explanation:
9) e/4-10=-20 add 10 on both sides
e/4=-10 Multiply everything by 4
e=-40
10) 0.4k-4+1.6k=14 combine like terms
2k-4=14 Add 4 on both sides
2k=18 divide both sides by 2
k=9
3x+67=130
3x=63
x=21
