Is x=3, y=2 a solution to the system of equations shown? Justify your answer. y = 2x - 4
3x + 2y = 8

It is NOT a solution to the system of equation

Step-by-step explanation:

you're given y already so you'll just be plugging it in

3x + 2y = 8

3x + 2(2x - 4) = 8

3x + 4x - 8 = 8

7x - 8 = 8

7x = 16

x = 2.28

As you can see X does not equal 2 so the statment of X = 3, Y = 2 is false. You can also plug in the values they gave you to see if it's true.

3x + 2y = 8

3(3) + 2(2) = 8

9 + 4 = 8

13 = 8

This statment is false which means the values they gave you is not a possible solution

d

step-by-step explanation:

in a an geometric explicit equation, the first number is the starting rate. in this case 10.
