Question

What is the solution to the following system of equations?
(metal will be given to person who helps me)
-8x - 6y = 52
8x + 0y = -16

Answer 1

does it really say \(0y\) ??!!

Answer 2

must be a computer generated question

Answer 3

my hw said exactly that

Answer 4

i take it online so its hard to understand the homework

Answer 5

Hello, SK:
I assume you know that a "solution" here signifies a point, (x, y), whose coordinates satisfy the given set of equations. Our job is to find such a solution.
I'm glad satellite has pointed out that that coefficient of " 0 " for y appears to be unusual.

Answer 6

With such a system, we need to eliminate one variable and solve the resulting equation for the other.

In

-8x - 6y = 52
8x + 0y = -16

note that -8x+8x = 0.

Please combine all like terms: -8x+8x=? -6y+0y=? 52-16= ?

Answer 7

x^2-6y^2=36 ? did i do it ok :((

Answer 8

Let's combine:

-8x - 6y = 52
8x + 0y = -16
-------------
0 -6y = 36

Please solve this resulting equation for y.

Answer 9

y=-6

Answer 10

Remember: "combine" signifies addition or subtraction. No squares result.

Perfect. Now that you have y=-6, how would you go about finding the value of x?

Answer 11

Hint: you have two equations relating x and y:

-8x - 6y = 52
8x + 0y = -16

You've found that y=-6. You could:
(1) substitute that y=-6 into the first equation and solve for x, or
(2) note that the second equation simplifies to 8x=-16 and solve this for x.

y = -6
x = ?

Answer 12

-2 is x

Answer 13

?

Answer 14

Very sorry for my slow response. Yes. x=-2.

Now, having obtained x=-2 and y=-6, how would you go about checking your answer?
