The first one would be the right one!
you just take all the y one side and the numbers on one side
so 8y+4= 6+3y
now 8y-3y= 6-4
therefore 5y = 2

Answer:
The sum is 2. ...........
Answer:
C) v≤-5
Step-by-step explanation:

Divide each side by 4,

Step-by-step explanation:
We have been given that David, Egil and Frances share money in the ratio 2:7:9.
Let 2x, 7x and 9x be the amounts of money that David, Agil and Frances get respectively.
We are told that Frances gets $80 more than David. So we can write this information in an equation as:

Now let us solve for x.


Now let us substitute
in 7x (amount of money that Egil gets).

Upon cancelling out 7 from numerator and denominator we will get,
Therefore, Egil will get $80.
Answer:
