X=first number
2x= second side
3.5x= third side


X+2x+3.5x=65

6.5 x= 65
Divide both sides by 6.5

X=10. First side
2x= 20. Second side

3.5x= 35 = third side

10, 20, 35

What is the solution to the equation PLS
brilliants [131]

Answer:

x=2.5

Step-by-step explanation:

the first thing you want to do is simplify like terms.

you could say this is as 4(x+7)=38

this can easily be solved algebraically.

first use distributive property on the four

this leaves you with 4x+28=38

next, subtract 28 from both sides

4x=10

now divide everything by four and you get x=2.5

-8n+4(1+5n)=-6n-14 show your work
dmitriy555 [2]

Answer:

n = -1

Step-by-step explanation:

-8n + 4 (1 + 5n) = -6n - 14

-8n + 4 + 20n = -6n - 14     Distribute

12n + 4 = -6n - 14            Combine Like Terms

18n + 4 = -14             Add 6 on Both Sides

18n = -18         Subtract 4 on Both Sides

n = -1              Divide Both Sides by 18
