Question

PLEASE PLEASE PLEASE IN THE NAME OF THE GODS HELP ME !!!!!!!!!

What is the value of the y variable in the solution to the following system of equations?

3x − 6y = 3
7x − 5y = −11

A.) −2

B.) −3

C.) x can be any number as there are infinitely many solutions to the system.

D.) There is no x value as there is no solution to the system

Answer 1

Im going to try this, I think.
) D(412)

3*708-2*412=1300
708+412=1120

2) C
x can be any number(infinte solutons)

3) B (x=−3)

Answer 2

You're the one doing the exam, right?

Answer 3

UHM NO . this is just algebra 1 .

Answer 4

Well set one equation to have x on one side and y on the other. then plug that x into the other equation

Answer 5

Wait I messed up, hold on.

Answer 6

okay sure (:

Answer 7

Step 1. 3x-6y=3
Step 2. 3x=3+6y
Step 3. x=1+2y (Here you divide each side by 3)
Step 4. You know that x = 1+2y, so you can plug that into the x of the other equation
Step 5. 7*(1+2y) - 5y = -11
Step 6. 7 + 14y -5y= -11
Step 7. 7 + 9y = -11
Step 8. 9y = -11 - 7
Step 9. 9y = -18
Step 10. y = -2

Answer 8

Tada :]

Answer 9

i just done all that but got the answer wrong too long to to do it again lol i used the method of elimination instead of substitution

Answer 10

Thanks, its much appreciated but it turns out I already had the answer ): sorry, I didn't notice till, like, now.

Answer 11

It's okay. Just remember you can substitute
