Question

what does x equal?

what does y equal?

(2x)+(4y)=16

Answer 1

X=2 and Y=3

Answer 2

It is x+2y =8 unless the ( ) has some special meaning like [ ].

So x = 8 - 2y and y = (8 - x)/2

Answer 3

This can't be solved with the information you've given, as there are an infinite number of possible values for x and a corresponding infinite number of values for y.

You could say that x equals anything you like, as any number will fit.

Answer 4

x=2

y=2

Answer 5

X=2

Y=3

Answer 6

x=4

y=2

2x + 4y = 2(4) + 4(2) = 8 + 8 = 16

Of course, x could also be 10 and y could also be -1.

2(10) + 4(-1) = 20 + -4 = 16

Another equation is needed, or like some others have said, you can solve for x in terms of y or solve for y in terms of x.

Answer 7

x = 2

y = 3

Answer 8

2x + 4y = 16

2(x + 2y) = 16

x + 2y = 16/2

x + 2y = 8

the maximum of the y:-

2(1) = 2

2(2) = 4

2(3) = 6<======== is the answer

2(4) = 8

if y = 4... therefore... x = 0

therefore...

y = 3

x = 2

Answer 9

you can have infinite number of answers because you have only one equation. any value of x can have a unique value of y. you should have another equation to single out your answers.

Answer 10

U require 2 equations to solve this...

Answer 11

2x + 4y = 16

x = 8 - 2y .... now insert that as "x" in the original equation:

2(8-2y) + 4y = 16

16 - 4y + 4y = 16

y = 1 ... now insert that value for y in the original equation:

2x + 4(1) = 16

2x +4 = 16

2x = 12

x = 6

Answer 12

Well I can't tell you the numbers for x and y because I'd need another equation, but I can tell you what each value equals.

X:

(2x)+(4y)=16

2x=16-4y

x=16/2-4y/2

x=8-2y

Y:

(2x)+(4y)=16

4y=16-2x

y=16/4-2x/4

y=4-x/2

Answer 13

(2x) + (4y) = 16

(2x4) + (4x2) = 16

8 + 8 = 16

x=4

y=2

Answer 14

x= 4

y= 2

Answer 15

x = 2 , 4 , 6 , ...

y = 3 , 2 , 1 , ...

Answer 16

2x=16-4y

      x=8-2y

4y = 16-2x

     y =(16-2x)/4

      y=4-x/2

Answer 17

For solving an equation of two variables , u need at least 2 equations.

with 1 equation , there can be no unique solution.(there can be many values of x and y satisfying the equation)

  

Answer 18

x = (16 - 4y) / 2 = 8 - 2y

y = (16 - 2x) / 4 = 4 - (x/2)

You can't solve for a unique value for the (x,y) pair with only one equation.  You can only solve for y in terms of x, or x in terms of y.

Answer 19

One equation and two unknowns. No solution.

If you want a solution, choose any x you want, and find y as follows.

4y=16-2x

y=4 - (1/2) x

Answer 20

You cannot solve a system of 2 variables with only 1 equation.  You need the same number of equations and variables in order to find a unique solution.

For example, if x = 2, then y = 3 which makes the equation true.

But x could also = 1.2987482356278562348 and there would be a corresponding value for y that would still make the equation true.

You could solve (sort of) by graphing, and shading the region in which all real numbers satisfy the equation.
