4(d-8)-5 = 9(d+2)+1
Assuming you're looking for d:
Use Distributive Property for both sides
4d-32-5 = 9d+18+1
Combine like terms
4d-37 = 9d+19
Take all d's to one side & numbers to other
-37-19 = 9d-4d
Simplify
-56 = 5d
Divide both sides by 5
d = -56/5
Answer:
umm im not sure if this is the answer but i believe it would be -$35
Step-by-step explanation: -7 x 5
Hello,
We don't need algebra to solve this.
I suppose the ages are 1,2,3,4
Their sum is 1+2+3+4=10.
To obtain 94 we must add 94-10=84 for 4 persons =>84/4=21 to each
Ages are
1+21=22
2+21=23
3+21=24
4+21=25
But if really want an algebric resolution:
Let's x the age of the youngest
x+1,x+2,x+3 the others.
x+(x+1)+(x+2)+(x+3)=94
==>4x+6=94
==>4x=88
==>x=22
Ages are 22,23,24,25.
The oldest friend is 25 years old.
