Question 2 (Multiple Choice Worth 2 points)

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

3x − 6y = 3
7x − 5y = −11

−2

−3

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

There is no x value as there is no solution to the system

Question 3 (Multiple Choice Worth 2 points)

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

3x + y = 6
6x + 2y = 8

0

Question 5 (Multiple Choice Worth 2 points)

The three Math Idol judges have been eliminating contestants all day! The number of one-step equations and two-step equations who have been eliminated today is equal to 1120. If three times the number of one-step equations minus twice the number of two-step equations is equal to 1300, how many two-step equations auditioned today?

1300

1120

708

412

Answer 2

Let me solve question 3 1st
1st eq:3x + y = 6
2(3x+y)=2(6)
6x+2=12
2nd eq:6x + 2y = 8
as 1st eq and 2nd eq has a different solution so it has no answers

Answer 3

ok

Answer 4

Question 4
1st eq: 4x + 2y = 6
2nd eq: x – y = 3
2x2nd eq: 2x-2y=6
using this eq +1st eq
6x=12
x=2

Answer 5

ok

Answer 6

Question 3
1st eq: 3x − 6y = 3
3(x-2y)=3
x-2y=1
whole eq x7
7x-14y=7
2nd eq:7x − 5y = −11
2nd eq - that eq
(-5+14)x=-18
9x=-18
x=-2

Answer 7

very helpful

Answer 8

and the last question:
I quite not understand the question..... sorry

Answer 9
