Answer:
-13
Step-by-step explanation:
We remove the -4 by adding 4 to each side:
3y = -43 + 4
Now we simplify to give:
3y = -39
So now we divide both sides by 3 to give our answer of:
y = -39/3
y = -13
We can substitute this into the original equation to check our answer:
-4 + 3(-13) = -43
-4 + -39 = -43

D≈2π(6371-1737.5)
d≈9267π
d≈29113.1km (to nearest tenth of a kilometer)
2. x =(6+√20)/-8=3/-4-1/4√ 5 = -1.309
Answer:
17=s+7
-7 -7
-----------
10 0
s=10
Step-by-step explanation:
-Subtract 7 from both sides
-Remove the 0 and the addition sign
-You are now left with the equation s = 10
-Once you check to make sure 10 + 7 = 17 you have your answer
Hope this helps :))
