If x + y = 12 and x = 2y, then x=

y = 4

x = 8

Step-by-step explanation:

here's the solution :-

we know, x = 2y

so,

=》x + y = 12

=》2y + y = 12

( because x = 2y )

=》3y = 12

=》y = 12 ÷ 3

=》y = 4

so, y = 4

now,

=》x = 2y

=》x = 2 × 4

( because, y = 4 )

=》x = 8

so, we get x = 8

the correct answer to your question is a. 4^4

good luck my friend!

hope this !

maybe if i you could me by giving me brainliest?

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
