Answer:
Max made a mistake in step 5.
He should have used division instead of multiplication.
Step-by-step explanation:
In step #5, he made the mistake of multiply 5/6 by 5/6. The reason why this doesn't work is because y is not a full y. When there isn't a number beside a variable, it is implied that it is 1y. To solve for y, you need 1y or else results or inaccurate.
In reality, 5/6 * 5/6 is equal to 25/36. If you divided 5/6 by 5/6, it is equal to 1, which makes y a full y.
Anna's age is A
Courtney's age is C
A=2C+6
You get this because it says that Anna is twice Courtney's age so you multiply Courtney's age by 2. Then it says that she is 6 more which is why you add six after you multiply by 2.
So your equation is
A=2C+6
We can simplify second fratction by divide 2
4/2=2
6/2=3
2/(3xy^3)
common denomenator
factor
3x^2y=3*x*x*y
3xy^2=3*x*y*y
LCD=3*x*x*y*y=3x^3y^2
multiply first fraction by y/y and second fraction by x/x
(5y)/(3x^2y^2)-(2x)/(3x^2y^2)=
(5y-2x)/(3x^2y^2)
Im guessing this is simplify so the answer would be
