The multipliers of this system of equations have been determined to create opposite terms of the x-variable.

12 (negative one-sixth x minus two-thirds y = negative 5) right-arrow negative 2 x + 8 y = negative 60.
5 (two-fifths x + one-fifth y = negative 9) right-arrow 2 x + y = negative 45

What is the value of y?
–30
–15
15
30

Answer:

15

Step-by-step explanation:

negative 2 x - 8 y = negative 60

2 x + y = negative 45

-2x - 8y = -60

2x + y = -45

Adding the two equtions:

-7y = -105

y = 15

The value of y is 15 for the system of equations -2x - 8y = -60 and 2x + y = -45. The correct option is C.

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The given system of the equation is:-

-2x - 8y = -60

2x + y = -45

The above equations are linear and two variables are x and y. To solve the above equation use the elimination method.

Adding the two equations it will eliminate the term and will give the value of y.

-7y = -105

Divide 105 by 7 to get the value of y.

y = 15

Hence, the value of y is 15 the correct option is C.
