Y = (2/3)x + 6
3y - 5x = 9

find an expression for y from the second equation:-
y = (5/3)x + 3
Now substitute this for y in the first equation:-
(5/3) x + 3 = (2/3)x + 6 Now solve for x:-
(5/3)x - (2/3)x = 6 - 3
x = 3
Now plug x = 3 into the second equation to find the value of y:_
3y - 5(3) =9
3y = 15+9 = 24
y = 8
So the solution is x = 3, y = 8

written as a set this is {3,8}.

____ [38]

Answer:

$(x+3)(x+9)$

Step-by-step explanation:

We are given the expression $x^2+12x+27$

This means that we are looking for two numbers that would add together to give us 12 and multiply to give us 27.

The two numbers that fit this description are 3 and 9.

This means that the factored form of the expression would be

$(x+3)(x+9)$
