Let x be Gabrielle’s age
Let y be Mikhail’s age
X=2y and x+y=84 so...
X=2y and x=84-y so by substitution of x,
2y=84-y
3y=84
Y=28

So Mikhail is 28
And Gabrielle is 56

Solve for y. 6x-4y=-16
musickatia [10]

y =  \frac{6}{4} x  + 4



Explanation:
1. you subtract 6x to get 4y alone. which will get you -4y=-6x-16
2. then you divide everything by -4 to get y completely alone.
This will get you the answer of y=6/4y+4
