✔ 最佳答案
(x,y) = (5,-1)So, x = 5 and y = -1.
Substitute :
3(5) + 6(-1) = 9
15 - 6 = 9
9=9
So it is correct.

To determine weather (5,-1) is a solution of 3x+6y=9, we will plug in
x=5, and y=-1 to 3x+6y=9.
So heres the solution:
3(5)+6(-1)=9
15-6=9
9 = 9 therefore, your solution in correct...

Hi,
This can be proved by substituting the given point on the line so that you get the LHS and RHS are equal.
3x+6y=9
Let us take the LHS 3(5)+6(--1) = 15--6 = 9 =RHS
So you get the required answer.

To determine whether (5,-1) is a solution of 3x+6y=9, we will substitute x=5 and y= -1 and check if these values satisfy the equation
3x+6y = 3*(5)+6*(-1) = 15 - 6
=9 which means equation is satisfied.
So, (5,-1) is a solution of 3x+6y=9
3x+6y = 3*(5)+6*(-1) = 15 - 6
=9 which means equation is satisfied.
So, (5,-1) is a solution of 3x+6y=9

3x+6y=9....I think the weather in Dallas ought to be sunny with that kind of a mathematical outlook. I mean, what do you think we paid for this stuff? Rain and tornadoes be damned! I want to see liquid sunshine! This thing on the right is telling me that it looks like I have a lot of punctuation. I DON'T CARE ABOUT MY PUNCTUATION! I don't need a robot telling me how to live my life or spell my words. This is just the beginning...the rise of the robots will be soon and swift. I KNOW ALL CAPS MEANS SHOUTING!! I AM SHOUTING!! BWARGH!

3x + 6y = 9
3(5) + 6(-1) = 9
15 + (-6) = 9
15 - 6 = 9
9 = 9
You are correct.
3(5) + 6(-1) = 9
15 + (-6) = 9
15 - 6 = 9
9 = 9
You are correct.

(x, y) = (5, -1)
3x + 6y = 9
3(5) + 6(-1) = 9
15 - 6 = 9
9 = 9
Yes, you are correct!
3x + 6y = 9
3(5) + 6(-1) = 9
15 - 6 = 9
9 = 9
Yes, you are correct!
